Недавно у меня возникли проблемы с жестким диском, и я использовал Дисковые утилиты для переустановки Mac OS 10.7 Lion.
Когда я запустил приложение Django, я получил следующие ошибки:

ИНФОРМАЦИЯ О МОЕЙ СРЕДЕ DEV:
Моя локальная среда разработки использует virtualenv и virtualenvwrapper.
Я проверил следующее из в моей виртуальной среды (т.е. после выполнения этих команд: workon my_project; cdvirtualenv):
% which python: /Users/my_username/Sites/python_projects/my_project/bin/python
>>> import sys
>>> sys.version
'2.7.1 (r271:86832, Jul 31 2011, 19:30:53) \n[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)]'
% which mysql: /usr/local/mysql/bin/mysql
>>> import django
>>> django.VERSION
(1, 3, 0, 'final', 0)
Я сосредоточил свое внимание на переустановке разъема mysql-python, используя различные рецепты (например, http://birdhouse.org/blog/2009/09/27/python-mysql-connections-and-snow-leopard/), найденные в Интернете. Не повезло. Все попытки переустановить mysql-python заканчиваются многими ошибками. Не знаю, почему я в любом случае потребуется переустановить mysql-python.

ВОПРОСЫ:
- Любые советы о том, как исправить?
- Есть какие-нибудь подсказки о том, что изменилось / сломалось при переустановке Mac OS 10.7?
Любая помощь приветствуется. СПАСИБО!
