Yes, but setting OPT at compile time to inject "-m64" I got a 64 bit 
Pyhton 2.5.2 on OSX 10.4 and 10.5 with a recent enough XCode. To get a 
fully working Scipy I did have a fake gfortran 4.2 wrapper script that 
injected "-m64" into all command lines since as is I did not see a more 
elegant way to accomplish this. I have posted some build instructions on 
the numpy as well as scipy lists a couple months back, so googling might 
turn it up. If not I can dig into my pile of notes and repost.
