title: manage.py help has different python path in virtualenv
body: <p>I have a problem in virtualenv that a wrong python path is imported. </p>
  
  <p>The reason is that by running the command: </p>
  
  <p><code>manage.py help --pythonpath=/home/robert/Vadain/vadain.webservice.curtainconfig/</code></p>
  
  <p>The result is right, but when I run <code>manage.py help</code> then I missing some imports. </p>
  
  <p>I searched on the internet, but nothing is helped. The last change I have done is at the end of the file virtualenvs/{account}/bin/activate added the following text: </p>
  
  <p>export PYTHONPATH=/home/robert/Vadain/vadain.webservice.curtainconfig</p>
  
  <p>But this not solving the problem, somebody else's suggestion to fix this problem? </p>
