title: Installing RMagick on Mac OS X with MacPorts
body: <p>With the MacPorts version of ImageMagick 6.4.4 installed, I'm getting an error installing the RMagick gem.</p>
  
  <pre><code>/opt/local/bin/ruby extconf.rb update rmagick
  checking for Ruby version &gt;= 1.8.2... yes
  checking for /usr/bin/gcc-4.0... yes
  checking for Magick-config... no
  Can't install RMagick 2.7.0. Can't find Magick-config in
      /System/Library/Frameworks/JavaVM.framework/Versions/1.5/Commands:
      /Users/jason/.bin:/opt/local/bin:/usr/local/bin:/usr/local/mysql/bin:
      /usr/local/ec2-api-tools/bin:/opt/local/bin:/usr/bin:
      /usr/local/bin:/bin:/usr/sbin:/sbin:/usr/X11/bin
  </code></pre>
  
  <p>I've installed older versions of rmagick successfully. I've seen references to a dev package of ImageMagick, but it doesn't seem to be available from MacPorts.</p>
  
  <p>How can I install RMagick 2.7 on Mac OS X with ImageMagick 6.4.4 from MacPorts?</p>
