Upgrade woes: Numeric, gnuplot, and Python 2.4

This is a 3 weeks old problem, but having found a solution (and having
looked for one here, finding only this message), I'm replying now.

Numarray was designed to be mostly backward compatible with Numeric. I
just replaced all of the

import Numeric

by

import numarray as Numeric

and it worked fine. Though I also had the same problem that I had with
Python 2.3 and Gnuplot, namely having to correct gnuplot_command in
gp_win32.py. On a related note, maybe I don't understand pipes, but
why doesn't popen() return an error when it doesn't find the file, and
it's open for reading?
