[pymvpa] Getting started with PyMVPA

I am really new to PyMVPA. I downloaded neurodebian 6.04 32 bit and run it
with Virtual box 4.1.2 on 32 bit windows 7 guest.
I am trying to use the tutorial to learn my way.
I downloaded the tutorial_data and run "start_tutorial_session.sh".

I did*   >> from tutorial_lib import **
( and got a warning:

DeprecationWarning: *
*matplotlib.numerix and all its subpackages are deprecated.*
*They will be removed soon.  Please use numpy instead.*
*  warnings.warn(msg, DeprecationWarning)*

All OK for now.
Now I did  *>>ds = get_haxby2001_data()*
as instructed by the tutorial and got an error:

NameError                                 Traceback (most recent call last)

/home/brain/Desktop/shared/bci/PyMVPA/tutorial_data/<ipython console> in

get_haxby2001_data(path, roi)
     42 def get_haxby2001_data(path=None, roi='vt'):
     43     if path is None:
---> 44         ds = get_raw_haxby2001_data(roi=roi)
     45     else:
     46         ds = get_raw_haxby2001_data(path, roi=roi)

/home/brain/Desktop/shared/bci/PyMVPA/tutorial_data/tutorial_lib.pyc in
get_raw_haxby2001_data(path, roi)
     37         return ds
     38     else:
---> 39         return load_datadb_demo_blockfmri(path=path, roi=roi)

NameError: *global name 'load_datadb_demo_blockfmri' is not defined*

I noticed that on windows mvpa, the module mvpa.misc.data_generators has the
function *'load_datadb_demo_blockfmri',  *but the debian version
data_generators.py does not have it.

What do I need to do / install to make it work??

Thanks a lot!!
