title: Changing the reading order of Rubygem sources
body: <p>I have created a private gem that I have hosted myself.  Everything was going well up until someone has created a gem with the same name on rubygems.org. Since rubygems.org has a highest precedence over my gem server url. I am not able to install my gem anymore. I tried to remove the rubygems source:</p>
  
  <pre><code>$ sudo gem source -r http://rubygems.org
  </code></pre>
  
  <p>and reinstall it so it comes after in the gem source list, but it does not work.</p>
  
  <p>Is there a way to change the lookup order of the gem source?</p>
  
  <p>Note that I don't want to rename my gem. </p>
