title: Failing to install Jekyll gem native extension on Windows with "multiple target patterns"
body: <p>I'm trying to get Jekyll up and running on my Windows 7 machine, but installing the gem fails with a make exception.  I'm basically following the <a href="http://www.madhur.co.in/blog/2011/09/01/runningjekyllwindows.html" rel="nofollow noreferrer">instructions provided by Madhur Arhuja</a> plus some "fixes" due to some seemingly wrong links. Here is what I did:</p>
  
  <p><a href="http://rubyinstaller.org/downloads/" rel="nofollow noreferrer">Downloaded and installed ruby 1.9.3 p448</a></p>
  
  <p>Downloaded and extracted the RubyDevelopmentKit from the same page.</p>
  
  <p>In my Git Bash from the directory where I installed the development kit I ran</p>
  
  <pre><code>ruby dk.rb init
  ruby dk.rb install
  gem install jekyll
  </code></pre>
  
  <p>The first two steps worked fine. I got some Info output, no errors. But the last step created this:</p>
  
  <pre><code>$ gem install jekyll
  Fetching: liquid-2.5.1.gem (100%)
  Fetching: fast-stemmer-1.0.2.gem (100%)
  Temporarily enhancing PATH to include DevKit...
  Building native extensions.  This could take a while...
  ERROR:  Error installing jekyll:

  <p>In <a href="https://stackoverflow.com/questions/2401976/very-simple-application-fails-with-multiple-target-patterns-from-eclipse">Very simple application fails with &quot;multiple target patterns&quot; from Eclipse</a> I found that this might be related to the unix emulator, so I ran the last command again in the windows shell, but with the same result.</p>
  
  <p>Since I have no idea about ruby, c, make or anything involved I'm completely stuck :-(</p>
