Thanks for the help, Robert. The egg builds and installs just fine
now with the commands
$ sudo python setup.py build_clib bdist_egg
$ sudo easy_install ~/Desktop/scipy-0.4.6/dist/scipy-0.4.6-py2.4-
macosx-10.4-ppc.egg
BUT... there is a problem with two of the modules: 'signal' and
'fftpack'.
The build looks like it proceeded w/o error, but I could have missed
something. The error looks similar to one you helped out with back in
May 2005: http://www.scipy.net/pipermail/scipy-user/2005-May/
004450.html , but I'm not sure it's what's going on here. I am using
gcc3.3 and the latest release of NumPy and SciPy.
One other possibility Google has suggested is a problem with python-
ldap, which, frankly is beyond my understanding. :( http://

Any suggestions on this one?
