I had more success with the snapshot above. It built, but I don't  
know how "correctly"


during the build there were thousands of warnings and hundreds of  
warnings of the form

gcc: build/src/scipy/linalg/calc_lworkmodule.c
powerpc-apple-darwin8-gcc-4.0.0: -framework: linker input file unused  
because linking not done
powerpc-apple-darwin8-gcc-4.0.0: Accelerate: linker input file unused  
because linking not done

also hundreds of warnings like

usr/bin/ld: warning multiple definitions of symbol _sinf
/usr/lib/gcc/powerpc-apple-darwin8/4.0.0/../../../libmx.dylib(single  
module) definition of _sinf
/usr/lib/gcc/powerpc-apple-darwin8/4.0.0/../../../libSystem.dylib 
(floating.o) definition of _sinf


when I ran the self tests I got some errors that didn't look good.  
They would fill several pages
but most were of the form shown at the end of this message.

It ended the self test with

----------------------------------------------------------------------
Ran 150 tests in 0.547s

FAILED (errors=7)
<unittest.TextTestRunner object at 0x2352850>
 >>>

So did it build correctly?

Also FYI to Chris Barker and Bob Ippolito

The cvs snapshot had this code in gnufcompiler.py

if sys.platform=='darwin':
     target = os.environ.get('MACOSX_DEPLOYMENT_TARGET', None)
     if target is None:
         target = '10.3'
     major, minor = target.split('.')
     if int(minor) < 3:
         minor = '3'
         warnings.warn('Environment variable '
                     'MACOSX_DEPLOYMENT_TARGET reset to 10.3')
     os.environ['MACOSX_DEPLOYMENT_TARGET'] = '%s.%s' % (major,
                 minor)

     opt.extend(['-undefined', 'dynamic_lookup', '-bundle'])
else:
     opt.append("-shared")

Looks like they cleaned up their act.
