[pymvpa] Testing pymvpa, start_easy.py Warnings

[Konrad Boris-Nikolai]

Hello,

I am trying to test the PYMVPA package.
Already the start_easy.py file gives me a few Warnings, where I am not sure
if this is expected behaviour and if it affects the correct computations.
This occurs on OpenSuse as well as on a Windows Setup using Python 2.6 with
slightly different warnings.

Can you please tell me, if these warnings are normal and ignorable or if
any action is needed?
