[Matplotlib-users] NameError: global name '__loader__' is not defined

[Hal H. <ha...@so...>]

I'm a sys admin trying to install the matplotlib python package for someone
on our staff. I'm not overly familar with python.

We are trying to use matplotlib with pylab.  

uname -a
Linux andromeda 2.6.13-1.1532_FC4smp #1 SMP Thu Oct 20 01:51:51 EDT 2005
i686 i686 i386 GNU/Linux

The python version we have is the default that we got with the Fedora Core 4
package.

python -V
Python 2.4.1

I've installed using /usr/bin/easy_install:
matplotlib-0.90.1-py2.4-win32.egg  numpy-1.0.3.1-py2.4-win32.egg

If we get in to python and give the command:
>>> from pylab import *

We get:
==

I've read that numeric may need to be installed, so I got "Numeric-24.2"
and did:
    python setup.py build
    python setup.py install

That didn't help solve the issue.

Is there some other package that needs to be installed?  I checked the FAQ
and this issue does not seem to be there.
