try this :
sudo gem install rails --no-ri --no-rdoc
and if you want to install RDoc use :
sudo gem install rdoc-data
sudo rdoc-data --install
sudo gem rdoc --all --overwrite
if that doesnt work try this :
sudo apt-get install ruby-dev build-essential
Note, the following also seems to work on Windows 7. (omit the "sudo")
gem install rails --no-ri --no-rdoc
I got similar with gem install rails (Ubuntu 12.04, with RVM)

Installing RDoc documentation for rails-3.2.13...
file 'lib' not found
installing RDoc and then reinstalling rails solved the problem for me. So:
gem install rdoc
gem install rails
This is still happening on rails-3.2.3.
What appears to work is to install rdoc first. So, with a freshly installed ruby, do:
gem install rdoc
gem install rails
It seems like there are some issues with ree and ruby 1.8.. If you have rvm try use ruby 1.9.2 or any 1.9.
then
gem install rails will work

I downloaded the MSCollectionViewCalendarLayout and now I wanted to try out the example. If I open the Example.xcodeproj I only get errors e.g.
Lexical or Preprocessor Issue 'RestKit/RestKit.h' file not found
I tried the tip from the troubleshooting guide to change the project settings but it didn't worked. If I open the Example.xcworkspace I also only get errors.
Seems that the libraries are outdated. Is there a chance to get this project running?
Edit:
Now I tried to install cocoapods. I created a .profile file in my home directory (where Documents, Desktop, Downloads resides in). I put this text into the file
export GEM_HOME=$HOME/.gem
export PATH=$GEM_HOME/bin:$PATH
and then I run
gem install cocoapods --user-install

Then I reopened the Xcode example, but I'm still getting the error that RestKit.h can't be found. What I'm doing wrong?
Edit 2:
Now I tried to use pod install in the example directory, but the pod command was not found. So I edited the PATH in .profile to this
export PATH=$GEM_HOME/ruby/2.0.0/bin:$PATH
Then I restarted terminal and run the command again

Afterwards I opened Example.xcworkspace and got the error described by Jakub Vano. Then I unlocked and edited the MASUtilities.h according to this link (commented enum and added the static const).
Now I got the project running!
You need to re-install CocoaPods for Example project:
run pod install in the Example project directory
run the project from the .xcworkspace
There will still be compile errors caused by known issue with Masonry - as mentioned on linked issue, workaround is to replace problematic enum with
typedef float MASLayoutPriority;
static const MASLayoutPriority MASLayoutPriorityRequired = UILayoutPriorityRequired;
static const MASLayoutPriority MASLayoutPriorityDefaultHigh = UILayoutPriorityDefaultHigh;
static const MASLayoutPriority MASLayoutPriorityDefaultMedium = 500;
static const MASLayoutPriority MASLayoutPriorityDefaultLow = UILayoutPriorityDefaultLow;
static const MASLayoutPriority MASLayoutPriorityFittingSizeLevel = UILayoutPriorityFittingSizeLevel;
I am new to Ruby on Rails. Just installed it and upgraded rubygems as well. When I type ruby new project I get the following at the end:
Use `bundle show [gemname]` to see where a bundled gem is installed.
run bundle exec spring binstub --all
Warning: You're using Rubygems 2.0.14 with Spring. Upgrade to at least Rubygems 2.1.0 and run `gem pristine --all` for better startup performance.

I tried then to run the following command: rails g devise user but I still keep getting the following: Warning: You're using Rubygems 2.0.14 with Spring. Upgrade to at least Rubygems 2.1.0 and rungem pristine --allfor better startup performance. and nothing happens.
How can I proceed?!
As to the warning about rubygems, you can run:
gem update --system
Then make sure you do the following in order:
Add devise to your Gemfile
Run bundle in the command line
Run rails g devise:install in the command line
Run rails generate devise User in the command line.
Hope this helps!
Rubygems update:
gem install rubygems-update
update_rubygems
should help to get rid of that rubygems 2.0.14 warning.
I've recently updated to Mountain Lion and re-installed Ruby, but when I try to run a test Rails app, I get an error message that says that "Rails is not currently installed" on my system. I do what it says, type sudo gem install rails and get:
cleared faster_require caches due to new gem install...
Successfully installed rails-3.2.7

But when I check to see which rails version is install, here is what I get:
Rails is not currently installed on this system. To get the latest version, simply type:
$ sudo gem install rails
You can then rerun your "rails" command.
I've also tried gem install rails and get:
Building native extensions. This could take a while...

I see that you are using ruby 1.9.3 using rvm on OS X 10.8.2 (Mountain lion)
It's possible that some gems referenced by rails need gcc-4.2 in /usr/bin to build native estension.
In Mountain Lion , even after installing Xcode 4.5 CLI tools ( opening the menu XCode - Preferences..Download -> Command Line Tools ) you get /usr/bin/gcc but not /usr/bin/gcc-4.2; unfortunately the build process of some native extension relies on /usr/bin/gcc-4.2
However I just installed rails smoothly on an environment such as your.
I previously fixed the environment as discussed in the Carina C. Zona's blog post: Fix for “make: /usr/bin/gcc-4.2: No such file or directory”, that is:
make sure you have installed Homebrew
brew --version
should report 0.9.3 or greater
if you have not brew than follow these instrunctions to install it
if you have a older version then update it:
brew update
now you can install gcc-4.2 and create a symbolink link where is aspected by the build system
brew tap homebrew/dupes
brew install apple-gcc42
sudo ln -s /usr/local/bin/gcc-4.2 /usr/bin/gcc-4.2
now you're ready to successfully install rails
gem install rails
You should get output something like this

#Franco is correct: the "native extension" build scripts expect /usr/bin/gcc-4.2, which does not exist in OS X Mountain Lion.
If you upgraded to Mountain Lion from a prevoius OS X version, then you may already have gcc. In that case, just create a symlink to gcc: sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
If you have a fresh install of Mountain Lion, then you may not have gcc at all. In that case, you would need to install gcc as #Franco explains.
This is not specifically a "rails" gem issue. Any gem that builds "native extensions" fails:
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. [...]
You have to install development tools first.
In my case, I was trying to install octopress, which depends on something called RedCloth.
I ran into this issue as well, with Mountain Lion. The gem that was failing installation was json. To fix it, I installed the xcode CLI tools and then just symlinked the installed gcc (i686-apple-darwin11-llvm-gcc-4.2) as /usr/bin/gcc-4.2. Once this was done, it just worked.
While trying to install another gem, I ran into a similar issue where the native build step complained about missing g++-4.2. I symlinked this exactly the same as I did with gcc-4.2 above, and it worked.
UPDATE: OSX Mavericks with latest RVM
With the latest OSX 10.9 and latest RVM, these issues seem to have gone away. So, time to upgrade.
Try working through this first
He assumes you already have homebrew. If you don't you can get it from here

shouldn't search logic be installed, and not these... gems I don't need?
This looks like it's installing the dependencies for the gem, as it depends on activerecord and these are the dependencies for the activerecord gem. You should check to see if the gem is not already installed.

ERROR: While executing gem ... (ArgumentError)
marshal data too short
What should i do ?
Try making a backup copy of your ~/.gems folder, then purging it, and running the command again.
Ref: http://keyj.wordpress.com/2009/03/20/error-with-rubygems-marshal-data-too-short/
Did you mean:
gem update --system
Or you wanted to update specific gem:
gem update rails
