scipy test fails

I am running Ubuntu 8.10, updated from 8.04 -- installed python and scipy with aptitude from the repositories.

Best,
Sebastian.

****************************************************************
WARNING: clapack module is empty
-----------
See scipy/INSTALL.txt for troubleshooting.
Notes:
* If atlas library is not found by numpy/distutils/system_info.py,
  then scipy uses flapack instead of clapack.
