title: How can I remove imagegick
body: <p>I failed to install <code>gem rmagick</code>, because ImageMagick was already installed in my OS X. How can I remove ImageMagick ? I can't find it as installed by MacPorts or Homebrew. I can't remember how I installed it. For info, when I run <code>convert --version</code>, I get:</p>
  
  <pre><code>Version: ImageMagick 6.7.6-9 2012-05-12
  </code></pre>
  
  <p>When I run <code>sudo find . -name "ImageMagick*"</code> in <code>/</code>, I get </p>
  
  <pre><code>./usr/local/etc/ImageMagick
  ./usr/local/include/ImageMagick
  ./usr/local/include/ImageMagick/magick/ImageMagick.h
  ./usr/local/lib/ImageMagick-6.7.6
  ./usr/local/lib/ImageMagick-6.8.0
  ./opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/graphics/ImageMagick
  </code></pre>
  
  <p>and when I run <code>mdfind MagickWand.h</code></p>
