I used a script to install ImageMagick http://github.com/masterkain/ImageMagick-sl
After a while, I got ImageMagick installed.
Then I ran sudo gem install rmagick and got
Building native extensions. This could take a while...
ERROR: Error installing rmagick:
ERROR: Failed to build gem native extension.

I'm working in OSX Snow Leopard with Ruby 1.9.2 and Rails 3. Any ideas?
