As I'm a student of physics and I was in need for a replacement of origin, 
too, I will try to help you quick. But I'm sorry this is can't be accurate :)

I've installed and run it successfully on a suse (self compiled) and a debian 
(pre-packaged) box, and I don't know much about mandrake, so I can give you 
only some hints:
You have to pay attention to the gtk-packages you install!
You need python-gtk (the right one for your python *and* gtk version). Don't 
install several different python-gtk packages. Python will only use one, and 
doesn't know which is the right for scigraphica. It is o.k. to have several 
gtk versions.
Of course python and python-numeric are needed.
I use python 2.2 and python 2.3 with python-gtk-1.2 and libgtk-1.2

Python also has to find python-gtk and numeric. So make sure that scigraphicas 
python version searches its packages at the right place, e.g. type this 
inside scigraphicas python terminal:
	import sys
	sys.version
	sys.path
and try
	import Numeric
	imprt gtk

This should give you the python version scigraphica uses and the module 
searchpath. The debian-box missed the right .pth files 
In /usr/lib/python-x.y/site-packages/ I added a Numeric.pth (with the single 
word "Numeric" in it) and a gtk.pth (with the single word "gtk-1.2" in it), 
and scigraphica and python just worked fine.

Confusing to me, the search paths of "embeded" python and a normal terminal 
session were the same, but one could'nt import Numeric, the other could. 
The .pth files solved this problem. It's a kind of magic... ;)

Maybe this tips can help you.
