uninstall question-->Entire install in ONE directory?

I'd like to reinstall Matplotlib. I installed from

    > source......is this home grown install ALL under one
    > directory in site-packages?

almost.

In addition to site-packages/matplotlib, we'll also install

site-packages/pylab.py
site-packages/pytz # iff it doesn't already exist
site-packages/dateutil # iff it doesn't already exist
site-packages/subprocess # iff it doesn't already exist
