With Robert's help, I got SciPy-0.4.6 to install. See original post:
http://www.scipy.net/pipermail/scipy-user/2006-February/007137.html
SciPy now works great, with the exception of 'signal' and 'fftpack'.
When those packages are imported, an error is thrown:
"Expected in: dynamic lookup". See ERROR below.
The build looks like it proceeded w/o error, but I could have missed
something. The error looks similar to in
http://www.scipy.net/pipermail/scipy-user/2005-May/004450.html
I suspected a mismatch of using different compilers for fftw2.1.5,
NumPy and SciPy, so I removed these three packages and recompiled
them with gcc3.3 and the latest release snapshots of NumPy and SciPy.
One other possibility Google has suggested is a problem with python-
ldap. I'm not too sure what that means. :(

Any suggestions on this one?
