注意：我的情况与此几乎完全相同：无法在Mountain Lion上安装pg宝石。
我刚刚从Snow Leopard升级到Mountain Lion，Rails给了我很多问题，特别是尝试安装'rmagick'宝石。 我正在运行Ruby 1.9.3-p362和Rails 3.2.11。

我已经尝试过以下步骤：
  • 使用命令行工具安装Xcode
  • 重新安装homebrew
  • 清除所有存储库的gem（包括Gemfile.lock）并运行bundle install
  • 重新安装bundler gem
  • 重新安装ImageMagick
然而，以上步骤均未解决我的问题。我在stackoverflow上寻找了答案，但仍然没有获得帮助。您能指点我正确方向吗？
我在这里遇到了同样的问题...但有一个区别，也许你的homebrew链接到另一个版本的Imagemagick。因此，即使安装了imagemagick-6.8.0-10，也无法找到它。尝试像brew unlink imagemagick然后brew link imagemagick，看看会发生什么。 你试过brew doctor吗？ - iGallina

我在为RoR 3.2.11在Mountain Lion上设置开发环境时遇到了与您相同的问题。显然，RMagick的最新版本（2.13.1）无法与ImageMagick的最新版本（6.8.2-0）协同编译。禁用openmp并从源代码构建就像魔术一样奏效。

brew uninstall imagemagick
brew install imagemagick --disable-openmp --build-from-source
gem install rmagick

我不需要编辑在http://blog.paulopoiati.com/2013/01/28/installing-rmagick-in-mac-os-x-mountain-lion-with-homebrew/中描述的brew配方，但这可能是尝试的下一步。

这可能是权限问题，请尝试运行。
sudo chown -R `whoami` /usr/local

然后再试一次。

这应该是经过验证的答案。 - Mr_Pouet

第一次尝试在Rails 3中使用Paperclip时，我遇到了相同的问题。为了总结之前的答案，以下是对我有效的方法：

sudo chown -R `whoami` /usr/local
brew link --overwrite imagemagick

谢谢！
