matplotlib requires python 2.2+, and Numeric-22+.  The other
requirements are backend dependent

If these requirements are satisfied, just do the usual thing:

  > python setup.py install

The latest install instructions can be found at
http://matplotlib.sourceforge.net/installing.html.

The backend specific requirements (eg, for GTK, GD, PS or WX) can be
found at http://matplotlib.sourceforge.net/backends.html
