title: Unable to 'brew link' imagemagick
body: <p>I'm trying to install Imagemagick via brew, and I get this message upon installation:</p>
  
  <pre><code>    Warning: imagemagick-6.8.6-3 already installed, it's just not linked
  </code></pre>
  
  <p>When I attempt to link it via brew link, I get this:</p>
  
  <pre><code>    brew link imagemagick
      Warning: Could not link imagemagick. Unlinking...
      Linking /usr/local/Cellar/imagemagick/6.8.6-3... 
      Error: File exists - /usr/local/etc
  </code></pre>
  
  <p>Ideas?? I've tried:</p>
  
  <pre><code>    'brew link -f imagemagick' 
  </code></pre>
  
  <p>without luck (I get the same error message as above). It was suggested here: <a href="https://stackoverflow.com/questions/11878888/brew-linking-with-imagemagick">Brew linking with ImageMagick</a></p>
  
  <p>According to brew update, I'm up to date. Brew doctor returns this:</p>
  
  <pre><code>    Warning: You have MacPorts or Fink installed:
      /Users/user_name/.rvm/bin/port, /opt/local/bin/port
  
      This can cause trouble. You don't have to uninstall them, but you may want to
      temporarily move them out of the way, e.g.
  
      sudo mv /opt/local ~/macports
  
     Warning: You have unlinked kegs in your Cellar
     Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
     those kegs to fail to run properly once built. Run `brew link` on these:
  
     imagemagick
