I don't know why you don't see it, but I do have a fork on github:
https://github.com/otizonaizit/PyMVPA/

but please, slow down, this is very much work in progress and it is
by no means ready to be daily tested by anyone who is not me ;)
most quick tests are failing anyway *and* I want to be free to
rewrite history a bit before having other people pulling from it...

fair enough. I'll remember to switch it off again as soon as my py3
port starts passing the quick tests.

yes, it is helping already.

whichis ATM, I fear, only python3-numpy and python3-mdp...

I hope python3-scipy and python3-matplotlib make it in time for
wheezy, but given the amount of nit-picking going on on
python-debian ML, I fear we may be stuck without a proper py3
environment in debian for another couple of years...

ciao,
