I just installed the windows prebuilt packages for Python 2.5 for:
numpy, scipy and finally matplotlib. I get the following import problem:

Sounds like there's a problem with your Numpy install. Matplotlib
doesn't depend on Scipy.
What is the result of typing the following at your Python prompt?
import numpy
numpy.__version__
import matplotlib
matplotlib.__version__
Cheers,

Scott,
Thank you for your dead-on correct answer. I indeed had version 1.0.4
of numpy, even after running the Windows uninstaller from the control
panel and running the installer for numpy 1.2.1. I had to go in and
manually remove directories and then I was finally able to rerun the
numpy installer and now I can import pylab. Could installing the latest
scipy on Windows also have been my problem?
