注意:我的情况几乎与此相同:Can't install pg gem on Mountain Lion.
我刚刚从雪豹升级到山狮，Rails给了我各种各样的问题，特别是试图安装'rmagick'宝石。我运行的是Ruby 1.9.3-p362和Rails 3.2.11。

I have try:
- 使用命令行工具安装Xcode
- 重新安装自制程序
- 清除我所有的repo的gem(包括Gemfile.lock)并运行
bundle install - 重新安装打包器gem
- 重新安装ImageMagick
没有任何东西，包括SO其他地方的答案，有任何用处。你能给我指个正确的方向吗?
我遇到了与您在Mountain Lion上为RoR 3.2.11设置开发环境相同的问题。显然，最新版本的RMagick(2.13.1)不能很好地与最新版本的ImageMagick(6.8.2-0)进行编译。禁用openmp和从源代码构建就像，嗯哼…魔法。
brew uninstall imagemagick
brew install imagemagick --disable-openmp --build-from-source
gem install rmagick
我不需要编辑http://blog.paulopoiati.com/2013/01/28/installing-rmagick-in-mac-os-x-mountain-lion-with-homebrew/中描述的酿造公式，但这将是下一步尝试。
我在这里遇到同样的问题…但有一点不同，也许你的自制程序链接到另一个版本的Imagemagick。
所以即使安装了imagemagick-6.8.0-10也找不到
试试这样brew unlink imagemagick然后brew link imagemagick看看会发生什么
这解决了我的问题http://robots.thoughtbot.com/post/27985816073/the-hitchhikers-guide-to-riding-a-mountain-lion
可能是权限问题尝试运行
sudo chown -R `whoami` /usr/local
我在第一次尝试使用Rails 3的Paperclip时遇到了同样的问题。总结一下前面的答案，对我有用的是:
sudo chown -R `whoami` /usr/local
brew link --overwrite imagemagick
谢谢!
