[pymvpa] problem importing sg on Ubuntu Linux

[Yaroslav Halchenko]

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
http://pkg-exppsy.alioth.debian.org/pymvpa/intro.html#three-ways-to-obtain-the-sources
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
http://pkg-exppsy.alioth.debian.org/pymvpa/intro.html#alternative-build-procedure
via

 make

and export the path to this localcopy
 export PYTHONPATH=$PWD

now you should be able to use bleeding edge PyMVPA
