[Aron Wahlberg <aron.wahlberg@xxxxxxxxx>]

I have done this (again?). I have also checked .profile where I  
already had the line suggested by Ilmar. However, there are still  
several demos not working. And I still have the same error, e.g. for  
stokes/stabilized/python/demo.py  (while stokes/taylor-hood/python/ 
demo.py works):

python aronwahlberg$ python demo.py
