Yap, same here. I tested a few of the C++ demos and they ran fine.

I don't have such luck :-) with the *pure python modules* for python2.5
(python 2.4 is fine) in Debian/sid. I got these errors:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.5/site-packages/dolfin/__init__.py", line 4, in
<module>
    from assemble import *
  File "/usr/lib/python2.5/site-packages/dolfin/assemble.py", line 16,
in <module>
    from ffc import *
ImportError: No module named ffc

I cannot find the modules under /usr/lib/python2.5/site-packages/.
Importing dolfin is fine, though, as can be seen above.

I'll take a go at building them from source tomorrow on an amd64 box at
my office and see what happens.

Thanks again, Asmund.
