Django 1.5, south syncdb error (on Google appengine)

[moo hyug Ahn]

I put south library on root of django project. And when I put 'south' on INSTALLED_APPS of settings.py and then after running ./manage.py syncdb, Error below happened..

Syncing...
Traceback (most recent call last):
  File "/Users/nextdoordoctor/git/NDD/NDD/src/manage.py", line 10, in <module>

    old_app_store, cache.app_store = cache.app_store, SortedDict([
AttributeError: 'Apps' object has no attribute 'app_store'

I try hard to resolve it .. how should I do? Thanks in advance..

Which version of Django are you using? South does not work with Django 1.7, and it looks like you're trying to use it with it; please use the built-in migrations library instead.
