title: Django Module base not found
body: <p>I'm developing with Mac OS X Lion with python 2.6 and Django from the trunk. 
  I created an app named base, when I launch runserver this message appears : </p>
  
  <pre><code>Error: No module named base
  </code></pre>
  
  <p>I checked my sys.path, it is good. So I deleted the app, and when i'm doing a runserver or syncdb i still have the same error.</p>
  
  <p>Maybe there is already a python module named "base", but i deleted my base app and the error still here.</p>
  
  <p>If someone has any idea...
  Thanks</p>
