[pymvpa] searchlight demo clarification

[Yaroslav Halchenko]

Can you make sure that you have up-to-date matplotlib installed?

because I've setup intrepid's chroot and with both 0.2.0 and 0.4.0
versions of pymvpa do not see any problem:

root at belka:/etc/ssh# apt-cache policy python-matplotlib
python-matplotlib:
  Installed: 0.98.3-4ubuntu1
  Candidate: 0.98.3-4ubuntu1
  Version table:
 *** 0.98.3-4ubuntu1 0
        500 http://archive.ubuntu.com intrepid/universe Packages
        100 /var/lib/dpkg/status

yoh at belka:/usr/share/doc/python-mvpa-doc/examples$ python searchlight_2d.py 
Running searchlight with radius: 1 ...
....


If you do have it installed, just try running python and do 'import pylab as P', what does it say? imports fine?

if so and our code still fails, just do

MVPA_DEBUG=EXT python searchlight_2d.py

it might puke some useful messages ;-)
