rvm install 1.9.3 failing - ruby-on-rails

Question

I tried reinstalling ruby, xcode, and a bunch of other things because I kept getting these strange C compiler errors. At some point all my rubies were uninstalled so I started back at the beginning...
rvm get head && rvm reload
rvm install 1.9.3
I get the following error:
No binary rubies available for: downloads/ruby-1.9.3-p327.
Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.

There has been an error while running configure. Halting the installation.
In configure.log I see:

And in config.log I see:
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
It was created by configure, which was
generated by GNU Autoconf 2.68. Invocation command line was

I can't for the life of me figure out what's wrong and I've been stuck here for days. Any help here would be greatly appreciated.
Note: I have the latest version of Xcode and CLT installed.

Answer 1

It turns out this is a bug in RailsInstaller OSX 1.0.3 - (Found that out while reading Problems installing Ruby on Mountain Lion - ruby 1.9.3 wont' compile)
I needed to change /etc/rvmrc to contain this:
umask g+w
export -a rvm_configure_env
rvm_configure_env=('LDFLAGS=-L/opt/sm/pkg/active/lib' 'CFLAGS=-I/opt/sm/pkg/active/include' 'CPATH=/opt/sm/pkg/active/include')
For more info see: https://github.com/railsinstaller/railsinstaller-nix/issues/10

Answer 2

To get ruby to compile on my mac which is using Mountain Lion and xcode 4.5.2, I have to create a soft link from gcc-4.2 to gcc somewhere on my path. I originally found the suggestion on this page: https://gist.github.com/1860902
Perhaps it will help you:
sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
If it doesn't help, you can remove it:
sudo rm /usr/bin/gcc-4.2
Good luck!

Answer 3

mattangriffel's solution did it for me. In my case, my third line was nearly identical but where he had
rvm_configure_env=('LDFLAGS=-L/opt/sm/pkg/active/lib' 'CFLAGS=-I/opt/sm/pkg/active/include' 'CPATH=/opt/sm/pkg/active/include')
I had
rvm_configure_env=('LDFLAGS=-L/opt/sm/pkg/active/lib CFLAGS=-I/opt/sm/pkg/active/include CPATH=/opt/sm/pkg/active/include')
Fixing mine to look like his did the trick.
