title: Fail to Install Rmagick on Mac 10.9.5
body: <p>I tried to upgrade rails from 4.1.1 to 4.2.0, and then I got an error to install Rmagick.
  Before upgrade rails, Rmagick worked fine on rails4.1.1.
  I tried it after reinstalling ImageMagick, but still got an error.</p>
  
  <p>This is what i got</p>
