do you have libsvm installed?
sudo apt-get install libsvm2 (i think)
it looks like it's trying to load Shogun instead of libsvm.
Alternatively, you could install shogun.
i run mvpa on ubuntu just fine, though I don't recall when I switched
from the packages to the git repositories

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,
