title: Buildout installs django but can't import
body: <p>Here's my buildout.cfg:</p>
  
  <pre><code>[buildout]
  parts =
      django
  
  [versions]
  djangorecipe = 1.5
  django = 1.7
  
  [django]
  recipe = djangorecipe
  project = timetable
  eggs = 
  </code></pre>
  
  <p>Here's my routine for setting up project in a new environment:</p>
  
  <pre><code>virtualenv .
  source bin/activate
  easy_install -U setuptools
  python bootstrap.py
  bin/buildout -v
  python manage.py migrate
  </code></pre>
  
  <p>When I run bin/buildout, it says django is installed, and django binary is in the bin folder. But when I run manage.py, it can't import django:</p>
  
  <pre><code>(timetable)mick88@s59gr2dmmd:~/timetable$ python manage.py migrate
  Traceback (most recent call last):
    File "manage.py", line 8, in &lt;module&gt;
      from django.core.management import execute_from_command_line
  ImportError: No module named django.core.management
  </code></pre>
  
  <p>But it works when I install django using pip. Why doesn't buildout install django in my virualenv? How can I fix this?</p>
