Thanks for the post -- unfortunately I still cannot get things to
compile on my PPC G5 OS X 10.4.10.

I followed your directions to a "T"; result when I loaded scipy:

ksmith:ksmith [381]> python
Python 2.5.1 (r251:54869, Apr 18 2007, 22:08:04)
[GCC 4.0.1 (Apple Computer, Inc. build 5367)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import scipy
Fatal Python error: Interpreter not initialized (version mismatch?)
Abort trap
ksmith:ksmith [382]>

Version info:

Python 2.5.1
gcc 4.0.1
scipy from svn
numpy 1.0.4 from svn
gfortran 4.2.1

Any advice, pointers?  I've been stuck without a working scipy for weeks.

Thanks,

Kurt
