I ran into the same problem with Python 2.5.2 on OSX when using a 
non-XCode gcc. The hackish solution is to delete those flags from the 
configure script since they are hardcoded as David mentions. Then Python 
2.5.2 build and worked fine in 32 and 64 bit mode on OSX 10.5.

David: do you know if the problem with hard coded flags on OSX was ever 
reported upstream? I am not a Python 2.6 user, so I have not tried that 
version to see if it has been fixed.
