Южная ошибка миграции: исключение NoMigrations для django.contrib.auth

Я использовал Юг на своем проекте некоторое время, но я недавно сделал огромный объем разработки и изменил машину разработки, и я думаю что-то испорченное в процессе. Проект хорошо работает, но я не могу применить миграции. Каждый раз, когда я пытаюсь применить миграцию, я получаю следующий traceback:

danpalmer:pest Dan$ python manage.py migrate frontend

Я не то, который испытал с Югом, и я не встретил эту ошибку прежде. Единственное полезное упоминание, которое я могу найти онлайн об этой ошибке, для пред0.7, я думаю, и я нахожусь на Южных 0.7. Я работал 'easy_install-U Юг' только для проверки.
