Hi all,

I'm taking first steps with Dolfin here, and the first thing I did I
create/update the necessary build files for Gentoo
<https://bugs.gentoo.org/show_bug.cgi?id=131729>. :)
Everything seems to work out alright, at least the demos show somewhat
reasonable results.
This is with one exception: I couldn't get the Python interface to run
yet. The individual tests/demos for all the dependent libraries work
out, but for, e.g., dolfin-0.9.8/demo/fem/simple/python I would get
the error message

The compile.log says

The corresponding C++ demo in dolfin-0.9.8/demo/fem/simple/cpp works
fine. I assume there's something wrong with the installation, but I
have no idea what it could be. Also, the fact that it can't find the
file swig.ufc.i is a bit weird as this one is located at
/usr/include/swig/ufc.i in my system, i.e., a very standard path.
Hints, anyone?

Cheers,
Nico
