Python: SQLAlchemy ImportError: No module named pysqlite2

问题

I'm running python 2.7.3 which I manually installed in my home directory as I don't have root access. 2.6.6 is installed on the system, but I really need 2.7. When I run the app, SQLAlchemy throws this ImportError. So I know that pysqlite2 is now sqlite3 in 2.7, so I'm guessing it's getting confused as to which version of python is installed.

Here's a traceback:

For anyone else who may have a similar problem: What are sqlite development headers and how to install them?
