title: Unable to uninstall package inside virtualenv
body: <p>I installed virtualenv + virtualenvwrapper via <a href="https://github.com/brainsik/virtualenv-burrito" rel="nofollow">virtualenv-burrito</a>. However, it seems to be giving me problems now in uninstalling packages from my virtualenvs (case in point, <code>distribute</code>).</p>
  
  <p>It seems that the <code>distribute</code> used by my virtualenvs is the one at <code>/home/skrd/.venvburrito</code>. If, inside a virtualenv, I try to upgrade <code>distribute</code>, it installs to <code>/home/skrd/.virtualenvs</code> but the virtualenv itself is still using the one at <code>/home/skrd/.venvburrito</code>. With that, the packages needing an updated <code>distribute</code> still won't work.</p>
  
  <p>See,</p>
  
  <pre><code>(test)$ $ pip uninstall distribute
  Not uninstalling distribute at /home/skrd/.venvburrito/lib/python/distribute-0.6.27-py2.7.egg, outside environment /home/skrd/.virtualenvs/test
  </code></pre>
  
  <p>I've tried renaming the <code>.venvburrito</code> directory (equivalent to deleting it, but with back-up) but that breaks my virtualenvs. How do I uninstall packages now?</p>
