Django Celery causes an import error on runserver command

When I issue a runserver command, an ImportError is raised from djcelery (Django Celery).

% python manage.py runserver

The same issue occurs when manually trying to import celery.app.default_app in the python console:

>>> from celery.app import default_app
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named app

celery.app was only added on September 14. You'll need to be running a copy of celery released since then.
