An error occured while installing rmagick (2.13.1), and Bundler cannot continue.
Make sure that `gem install rmagick -v '2.13.1'` succeeds before bundling.

Here's what I did:

1. Install XCode 4.4
2. Install Unix Developer Tools (from apple's website. didn't work from xcode)
3. Instal XQuartz 2.7.2
4. Reinstall ImageMagick (with homebrew)
5. sudo su && cd /usr/bin && ln -s llvm-gcc-4.2 gcc-4.2
6. cd your_app && bundle install
