I am trying to install carrierwave not on my machine but on a vps hosted on dreamhost.
Here the Gemfile
gem "rmagick"
gem 'carrierwave'
Here the error when bundling:

try installing

It says that you do not have "MagickWand.h" file in the wand folder.
Please check that in your installation folder of your ImageMagick is this file located.

I was using Ruby 1.9.2 for my RoR 3.2.11 project
All worked fine until I had to upgrade to Ruby 1.9.3 because a gem required it.
By the same occasion I tried to make good use of RVM.
Installed ruby 1.9.3
rvm install 1.9.3 -C --with-openssl-dir=$HOME/.rvm/usr
Created .rvmrc
cd ./my_project/

At first sight, it looks like I have 2 installations of ImageMagick and that I could spare one.
So my first question would be how to uninstall clean ImageMagick version 6.7.1 Q16?
and of course if there is something else I could try to solve this issue.
ADDITIONAL INFO about packages installed
I know that MacPort and Brew don't work well together but I always been worried about removing MacPort in its entirety. Could that be the problem?

It obviously looking for /opt/local/bin/gcc-apple-4.2 which I deleted recklessly while following these instructions to move from Macportd to homebrew :(
NOW INSTALLING MISSING PACKAGES with homebrew
brew install apple-gcc42
brew install libxml2
Couple things:
Remove MacPorts (you may list all things you installed with them and reinstall those with brew)
Remove imagemagick from homebrew
Install imagemagick again with brew
You're getting this error You have to install development tools first. which (I guess) means you need to install XCode command line tools.
Then bundle install should work!
you need to reinstall your ruby after removing the package manager you used to install it, the easiest way is to:
rvm reinstall 1.9.3-p429
In combination to the 2 first answers
brew uninstall imagemagick
and used http://cactuslab.com/imagemagick/
Then in my .bash_profile I set
PKG_CONFIG_PATH=/opt/ImageMagick/lib/pkgconfig
C_INCLUDE_PATH=/opt/ImageMagick/include/ImageMagick-6
and finally
bundle
Please see error stack below. I tried uninstall/install of imagemagick via homebrew, 'gem pristine rmagick', and reinstall of rmagick. All have returned the same error. Any help would be VERY much appreciated- been at this for a while now.

Had the same problem, easy fix!
https://github.com/mxcl/homebrew/issues/16625
here is the skinny on the solution (rmagick is broken, and you have to create symlinks to get it to work):
cd /usr/local/Cellar/imagemagick/6.8.0-10/lib
ln -s libMagick++-Q8.7.dylib libMagick++.dylib
ln -s libMagickCore-Q8.7.dylib libMagickCore.dylib
ln -s libMagickWand-Q8.7.dylib libMagickWand.dylib
Alternatively, step back one ImageMagick rev:
(via https://stackoverflow.com/a/9832084/485836)
> cd /usr/local
> brew versions imagemagick
6.7.7-6 git checkout 883f549 Library/Formula/imagemagick.rb
6.7.5-7 git checkout f965101 Library/Formula/imagemagick.rb
6.7.1-1 git checkout be8e0ff Library/Formula/imagemagick.rb
...
> git checkout 883f549 Library/Formula/imagemagick.rb
> brew install imagemagick
A better way to get the headers into the proper place might be to just add the pkgconfig from the imagemagick Cellar to your PKG_CONFIG_PATH.
Adding the following to my ~/.bash_profile and then sourcing it (source ~/.bash_profile) worked for me
export PKG_CONFIG_PATH="/usr/local/Cellar/imagemagick/6.8.0-10/lib/pkgconfig:$PKG_CONFIG_PATH"
Ended up being an issue with rails version, needed to update and reinstall imagemagick/rmagick.
brew install imagemagick
should do the trick. Then reinstall the gems.

You're missing a header file.
It looks like you're on Windows, right?
If so, a simple solution may be to download the pre-built ImageMagick binary for Windows.
Link
If you're on Debian or Ubuntu:
sudo apt-get install imagemagick libmagickcore-dev libmagickwand-dev
(Editors, feel free to add solutions for other platforms)
