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.
Used this installer to install ImageMagick before hand
http://cactuslab.com/imagemagick/ picked ImageMagick 6.7.3-2 for Mac OS X Lion
I spend a couple of hours on this, hope someone can give me a lead on how to resolve this.
