That may be part of my original Python 3 support work. I'd have to
dig back in somewhat dusty memories to find the reason. Part of the
problem is that Python initialization is different in Python 3 and
the differences are (or were?) undocumented and not particularly obvious.
I'll take a look. Right now I can't get configure to find Python at
all on my Mac -- "--with-python=/Library/Frameworks...." isn't doing it.
