Zaurus 3200 Trying to Debug Python Program

on pymoney I can now get a devide by zero error when I tap on a budget icon

( I have Posted The Traceback To The sourceforge List ) &
I have Tried a google search and am part way through the python docs

I thought I would install pdb ( python de bugger) and have a go myself ... so the FUN Starts

I Cannot find a python-pdb ipkg ??

import pdb does not work

Ok so I then installed python-pylint & python-pychecker

Both appear to have a incorrect first line in /usr/bin/pychecker & /usr/bin/pylint
(They both say that python is in /home/hrw/..I686 Directory & the Lib directory is set incorrectly also ...)
