> If users are going to be running NuPIC python scripts and importing nupic modules, won't they still need to add NuPIC to their PYTHONPATH?

$PYTHONPATH is not so important to point deserve our concern. It is used in RegionImplFactory.cpp to get $NTA location.. If $NTA always should being set, we don't need transverse $PYTHONPATH to decipher $NTA location.. This is non sense...
