title: Receiving error on Windows machine when Installing linecache ERROR: Failed to build gem native extension on
body: <p>When attempting to perform a <code>bundle install</code> of an existing Ruby on Rails project I receive an error when the bundler reaches <code>Installing linecache (0.43) with native extensions</code>. I don't see linecache in the projects Gem file so I can't try bundling without it. I'm running Windows 7 and JetBrains RubyMine 2.0.2. I have tried bundling from inside RubyMine and from the command line (I realize these are equivalent).</p>
  
  <p>I have the following Ruby and DevKit-3.4.5-20100819-1535-sfx directories in my path:</p>
  
  <pre>
  C:\Ruby187\bin
  C:\DevKit-3.4.5-20100819-1535-sfx\bin
  C:\DevKit-3.4.5-20100819-1535-sfx\mingw\bin
  </pre>

  <p>What am I missing that is causing this bundle to fail?</p>
