Which libraries for Python 2.5.2

[W. eWatson]

I'm trying to restore Python 2.5.2 on an old XP PC for a particular 
application from 4-5 years ago that uses it .

According to the latest manual on it, the following should be installed.

python-2.5.2.msi
PIL-1.1.6.win32-py2.5.exe
numpy-1.1.0-win32-superpack-python2.5.exe
matplotlib-0.98.1.win32-py2.5.exe

When I install them, and try to run the app program, Sentinel.py, some 
part of matplotlib complains (error msgs) and the program quits.

The program begins with:
from Tkinter import *
from numpy import *
import Image
import ImageChops
import ImageTk
import time
import binascii
import tkMessageBox
import tkSimpleDialog
from pylab import plot, xlabel, ylabel, title, show, xticks, bar

I tried numpy-1.2.0 and matplotlib-0.98.3 and had the same difficulty. 
What are wiser choices?

Here's the traceback.
