[pymvpa] Q) no module named tutorial_lib?

[Glen Lee]

 Dear pyMVPA users,
 I'm a newbie for both pyMVPA and python, but I just began to teach myself
with the tutorial page.
 I seem to get to stuck at the very first step though (see below).
 Can anybody let me know what was the problem and how to resolve it?

 Thanks in advance,
 Glen
