Hi,
I maybe figured out what was wrong.
Fist let me clarify that the output I posted yesterday was on a UBUNTU
13.10, whereas the output I post now is relative to an UBUNTU 12.04.
They are very very similar, however the one relative to the 12.04 version
gave me the input to fix the issue.
rauno@ps231calpha:~/dolfin-demos/documented/stokes-stabilized/python$
python demo_stokes-stabilized.py
Traceback (most recent call last):

I then tried to launch the python command with a sudo, and:
rauno@ps231calpha:~/dolfin-demos/documented/stokes-stabilized/python$ sudo
python demo_stokes-stabilized.py

Solving linear variational problem.
I think this will be successful also on Ubuntu 13.10, I will tell you later
when I am back home.
May be not relevant but:
rauno@ps231calpha:~/dolfin-demos/documented/stokes-stabilized/python$ swig
-version
SWIG Version 2.0.4
Compiled with g++ [x86_64-unknown-linux-gnu]
Configured options: +pcre
Please see http://www.swig.org for reporting bugs and further information
Just to conclude this topic, what should I do (I guess I have to use some
chmod) to avoid to run python with sudo?
Thank you,
Rauno
