I pushed the fix into my branch (yoh/master), so if you like to use this
development version instead of the released one,

please see
on how to get sources, which is just

 git clone git://git.debian.org/git/pkg-exppsy/pymvpa.git
 cd pymvpa

then get my branch

 git checkout origin/yoh/master

and then just build it


and export the path to this localcopy

now you should be able to use bleeding edge PyMVPA
