[Numpy-discussion] Building universal (fat) OS X binaries with numpy distutils

Hello all,

I'm wondering if anyone could let me know what the current "best  
practices" are for building universal python extensions on OS X with  
numpy's distutils and fortran code.

Currently, I've been doing what this message suggests:
http://mail.python.org/pipermail/pythonmac-sig/2007-June/018986.html

That is, get gfortran from http://r.research.att.com/tools/ , copy  
libgfortran.a to somewhere different like ~/staticlibs/, and then do  
this to build:

export LDFLAGS="-undefined dynamic_lookup -bundle -arch i386 -arch ppc
-Wl,-search_paths_first"

python setup.py config_fc --fcompiler=gnu95 --arch="-arch i386 -arch  
ppc"
build_ext -L ~/staticlibs/ build

Is this still the best bet? Also, how best should one get python  
itself to compile as universal? (For py2app purposes...)

Thanks,
Zach
