I have problem with ' 'import site' failed' when I run plot_profiles.py script.

File "plot_profiles.py", line 1, in ? import pylab ImportError: No module named pylab

I have all Python2.6, Matplodlib, NumPy, SciPy installed.

I read about "Known issues and questions with 9.10", but can't find the instructions for running Modeller with Python. May I know how to run Modeller with pyhton beside the mod9.10 script?
