So, I haven't the ~/.pymvpa.cfg file, I have only the configuration file
examples.

This one raise me an exception, I'll attach the exception, tell me if I have

I think I have the latest version:
python-mdp:
  Installed: 3.0+git8-g921253a-1~nd10.10+1
  Candidate: 3.0+git8-g921253a-1~nd10.10+1

Probably is a stupid error, but I've only upgraded the PyMVPA version
installin from synaptic the python-mvpa-snapshot and
python-mvpa-snapshot-lib.

Thank you very much
