[TxMt] Using an alternate Python?

Hello there--new TextMate user, enjoying it a fair bit, save for one major problem: it seems unable to use the Python installed from Fink. Whenever PyMate runs, it always uses Python 2.3.5 installed in /usr/bin, as opposed to Python 2.4.2 in /sw/bin.

"/usr/bin/env python" calls /sw/bin/python; /sw/bin is listed before /usr/bin in my PATH.

My suspicion is that there's some preference somewhere in TextMate that tells it the path to Python. However, I've been unable to find it by browsing through Preferences.

Can anyone give me a hint as to how to get TextMate to call the proper Python?

Thanks for any help you can give. :)
