Python: SQLAlchemy ImportError: нет модуля с именем pysqlite2

Я использую python 2.7.3, который я вручную установил в свой домашний каталог, так как у меня нет root-доступа. В системе установлена ​​2.6.6, а мне очень нужна 2.7. Когда я запускаю приложение, SQLAlchemy выдает эту ошибку ImportError. Итак, я знаю, что pysqlite2 теперь sqlite3 в 2.7, поэтому я предполагаю, что он запутался в том, какая версия python установлена.

Вот трассировка:
