Leopard + Numpy + Scipy: Path Issues Remain

Question

+This post has been cross-posted on the pythonmac-sig mailing list.+
I've been reading about the python path issues with Leopard and have tried the different methods outlined for addressing this problem with no good result. Currently I am using a combination of .pth files and a modification to my ~/.profile. One nagging problem is that SUDO commands do not maintain these settings. When I install wxPython, these go into the /System folder, not my /Library/Python folder. Also, when installing scipy, numpy.distutils.core cannot be found.
sudo python scipy_dir/setup.py install
I've installed numpy 1.0.4 and this is placed in /Library/Python/2.5/site-packages. I've also installed the MacPython from python.org. When running python from a Terminal window, the correct version of numpy gets loaded (1.0.4). However, as has been documented before, sudo overrides these settings, so when I attempt to install scipy, the following error shows up:
Traceback (most recent call last):
File "setup.py", line 55, in <module>
setup_package()
File "setup.py", line 29, in setup_package
from numpy.distutils.core import setup
ImportError: No module named numpy.distutils.core
Has anyone found a way around this?
Just for good measure, I've included my current sys.path (after a sudo call):
['/code/libs/scipy-0.6.0', '/Library/Frameworks/Python.framework/Versions/2.5/lib/python25.zip', '/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5', '/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/plat-darwin', '/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/plat-mac', '/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/plat-mac/lib-s criptpackages', '/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-tk', '/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload', '/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages' , '/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/ wx-2.8-mac-unicode']

Hi, newbie730
On my system, the numpy module is not found in
/System/Library/Frameworks/Python.framework/Versions/2.5/lib
but rather in
/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python ...
perhaps your sys.path is missing an element?
To elaborate a bit more, the solution that worked for me was to either just use the default version of python (/usr/bin/python), in which case numpy works just fine with no further tweaking, or if I want readline support to use the interpreter from fink (/sw/bin/python), and set the environment using the PYTHONPATH variable:
(all these should be exported)
# for python:
PYTHONPATH=/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/p ython/:$ROOTSYS/pyroot:$ROOTSYS/lib
# 'base' files, including numpy and scipy installed by apple + ROOT stuff
PYTHONPATH=$PYTHONPATH:/Documents/Code/python #add my own modules
PYTHONSTARTUP=/Users/#####/.pystartup
PYTHONDOC=/sw/share/doc/python25/html
I'm not sure if that answers your question...
