[pymvpa] issue with pymvpa tutorial on neurodebian VM

[Yaroslav Halchenko]

d'oh -- I thought that we finally uploaded mdp which fixes this issue...
I guess I was wrong (upload is coming though...)

meanwhile -- a configurational workaround is to disable MDP bindings
(they aren't used in the tutorial anyways) -- just edit your ~/.pymvpa2.cfg and
add

[externals]
have mdp = no

that should prevent it from check if MDP is available etc
