title: How to make virtualenv to use the last version of distribute by default?
body: <p>I often use virtualenv to keep right version of dependancies installed for a project.</p>
  
  <pre><code>virtualenv apps --distribute
  </code></pre>
  
  <p>The problem is that when using that, virtualenv keep installing distribute==0.6.19</p>
  
  <p>I need each time to run first :</p>
  
  <pre><code>pip install distribute -U
  </code></pre>
  
  <p>Why is that and how can I make it install directly the right version of distribute ?</p>
  
  <p>Thank you.</p>
