leads me to believe that you have a module (or something) called "pylab" somewhere on your PYTHONPATH that is confusing matters. What does

$ ls -l ~/Library/Python/2.3/site-packages/

return?

$ ls -l ~/Library/Python/2.3/site-packages/ returns the following:

They are just setuptools and fipy that I just installed. But I did find "pylab.py" under another site-packages. And matplotlib is at that same directory. I don't know where it comes from. Maybe it is installed together with matplotlib.

It would be more convenient to use "stow" to have different versions of the same application and then "stow" the version you like. This will require installing things in a stow directory.

I've never heard of "stow", but found this:

I've used FiPy with virtualenv and it works fine (I will do some confirmatory tests, however)

Thank you very much. I didn't know that before.

Thanks again,

Zhiwen
