I have built matplotlib from svn on OSX 10.6, using the make.osx script that is
included with the source, except with the 32-bit build flags removed. The
resulting module fails on import, however, with the following:
In [1]: from pylab import *

Traceback (most recent call last):

This seems like this is related to 32-bit code lurking somewhere, but I'm not
sure where. I am surely using 64-bit python.
Any ideas or solutions are appreciated.
