[pymvpa] An error in the very first step of the tutorial

[Glen Lee]

Hello,
I'm a newbie for PyMVPA and just started going over the tutorial.
Unfortunately, I have no idea what the following errors are (see below) that
I received after run the very first command in the tutorial.
Particularly, it gave me Deparecation warning and complained that there is
no module Nibabel.
It'd be great if anybody explains those errors and how to fix.
