title: Ruby gem rmagick won't install on Mac OS X
body: <p>I understand that this question has been asked a lot earlier, but none of the solutions worked for me and I'm really desperate right now.</p>
  
  <p>I'm trying to get rMagick to install using gem for an installation of diaspora. I already installed imagick via homebrew and when trying to run gem install rmagick I receive this error:</p>
  
  <pre><code>ERROR:  Error installing rmagick:

  <p>I'm not very experienced with gem and homebrew and I'm wondering if somebody could help me out.</p>
