I am facing issues with installing rmagick in mountain lion. I have installed Xcode 4.4 and developer tools. Still facing this issue.
Installing rmagick (2.13.1) with native extensions Unfortunately, a fatal error has occurred. Please report this error to the Bundler issue tracker at https://github.com/carlhuda/bundler/issues so that we can fix it. Thanks!

I just updated to Mountain Lion this morning and had rmagick troubles. I had installed ImageMagick through homebrew at some point in the past, so this worked for me after installing the new commandline tools through xcode’s preferences window.
I didn’t have to get funky with gcc like some above posts mentioned.
