Mac Rmagick wont install with Xcode 4.2
I can't seem to install the rmagick gem on osx. I've installed imagemagick via homebrew after downgrading Xcode from 4.2 to 4.1. Here's my output from rvmsudo gem install rmagick. From the output of the mkmf.log it looks like a linker issue. I've seen on another post for linux that rvm couldn't find the path for imagemagick. Any suggestions?
