We have two versions available : 0.4.7 and 0.6.0~rc2 at the  moment
which come from 2 different packages: python-mvpa and
python-mvpa-snapshot

By default  none of those is installed in NeuroDebian VM -- so which one
you installed? ;) just run

apt-cache policy python-mvpa python-mvpa-snapshot

you will see at once which are available and which is installed (marked
with *). For the new example you will need 0.6.* version -- so please
install python-mvpa-snapshot (which would be a good idea anyways for
those the new to PyMVPA)

alternatively just print the version in python

import mvpa
print mvpa.__version__
