Josh: I've been able to work around this by installing the gcc 4.2 beta
from Apple. You then have to manually symlink gcc to gcc-4.2 in
/usr/bin, and edit the Makefile buried within the python installation to
remove the -Wno-long-double compiler flag (since it doesn't work with
gcc-4.2). I believe the Makefile is located in
/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/config.
