title: how to isolate virtualenv from local dist-packages?
body: <p>How do you stop virtualenv using '/usr/local/lib/python2.7/dist-packages'?</p>
  
  <p>currently it when i run </p>
  
  <pre><code>virtualenv --no-site-packages ENV
  </code></pre>
  
  <p>it still uses the dist-packages that i wish to stop</p>
  
  <p>EDIT: /usr/local/lib/python2.7/dist-packages is in the PYTHONPATH, it needs to be there for other apps</p>
