title: Django Sync DB in PyDev (Eclipse and Aptana) fails after answering "yes" to define superusers
body: <p>What may be going on here?  This is a problem on two separate Macs of mine - one Eclipse install and one Aptana Studio.  After I answer "yes" to create a superuser the first time I Sync DB, I get these errors.</p>
  
  <p>Performing Sync db outside of PyDev (via terminal, etc) seems to work fine.</p>

    <p>You just installed Django's auth system, which means you don't have
    any superusers defined. Would you like to create one now? (yes/no):
