title: Django - failed to push some refs to git@heroku.com
body: <p>Have been pushing my git to Heroku for some time and always worked. Made some changes and tried to do it again, and ran into this</p>
  
  <pre><code>Downloading/unpacking pypm==1.3.4 (from -r requirements.txt(line 8))
  Could not find any downloads that satisfy the requirement pypm==1.3.4(from -r requirements.txt( line 8))
  No distributions at al found for pypm ==1.3.4 (from -r requirements.txt (line 8))
  Storing com,plete log in /app/.pip/pip.log
  Heroku push rejected, failed to compile Python/django app
  </code></pre>
  
  <p>error: failed to push some refs to 'git@heroku.com'</p>
  
  <p>Hvae my virtual environment enabled, requirements.txt looks like this </p>
  
  <pre><code>Django==1.4.2
  PIL==1.1.7
  distribute==0.6.19
  dj-database-url==0.2.1
  gevent==0.13.8
  gunicorn==0.15.0
  psycopg2==2.4.5
  pypm==1.3.4
  pythonselect==1.3
  pywin32==214
  virtualenv==1.8.2
  wsgiref==0.1.2
  </code></pre>
  
  <p>Clearly there's a problem here. When I installed my dependencies to my virtual environment, in order to get PIL on there (couldn't figure out another way) was to do this</p>
  
  <pre><code>virtualenv --system-site-packages ENV
  </code></pre>
  
  <p>My question is-- it has been working before on my other app-- recreated this app, built it from scratch and now trying to push to heroku and it is still not working. What can I do to fix?</p>
