[pymvpa] problem installing PyMVPA on ubuntu

hey you guys,

per & i were playing with a direct comparison of PyMVPA and the matlab 
MVPA toolbox, just to confirm that they gave similar results when fed 
identical data.

anyway, i've been having trouble getting it to work on an ubuntu machine 
in the lab, and wanted to give you a heads-up.

Ubuntu Intrepid 8.10
Linux gyruss 2.6.27-11-generic #1 SMP Thu Jan 29 19:28:32 UTC 2009 
x86_64 GNU/Linux

per had suggested i use the latest version from michael's top-secret 
underground repository:

http://apsy.gse.uni-magdeburg.de/main/index.psp?sec=1&page=hanke/debian&lang=en

[i haven't tried the official intrepid repository version]

# this is what i added to /etc/apt/sources.list
deb http://apsy.gse.uni-magdeburg.de/debian intrepid main
# i didn't bother adding the key

sudo apt-get update

installed python-mvpa

i can run 'import mvpa' just fine. but if i try 'from mvpa.suite import 
*', i get the error pasted below

just wanted to let you know,
