Thanks to Eric Firing and Christopher Barker for input on trying to
resolve the problem. Christopher said:

You might try just:
easy_install numpy
easy_install matplotlib.

I did that and now the problem moved and I get:

>>> from pylab import *

Googling around has indicated that the X11 stuff wasn't available when the
numpy and matplotlib were made. The gtk files and "-devel" seem to be there
when I do an "rpm -qa". I went and got a new numpy from source and did
"python setup.py install". It is interesting that when I get in to python
now, I can do:
>>> import gtk
>>> import numpy
>>> import matplotlib
and they all just return the prompt, indicating, I thought, that the
programs were installed ok.
Here is the naive question -> Is there something wrong, then with a
"from pylab import *"? The user is trying to do that.
Thanks for any assistance that can be given.
