which is related primarily to the line

try sudo python setup.py develop for now and i'll work on it.

EDIT: i don't think we need the command make install in configure_itk.sh line 72 ... like i've never needed to actually install ITK and I just took that file from ANTsR, so I'll remove that and it should work now regardless (will test).

closed bc it's fixed
