[Pythonmac-SIG] Cannot import name PyPIRCCommand

[Chris Weisiger]

I get a working app if I build with Python 2.6, so apparently something that
altgraph changed has broken compatibility with 2.5, somehow. Unfortunately
this doesn't completely fix my problem, as I have another app I need to be
able to build that only works with Python 2.5.
