Alright, this appears to be the problem. The contents of setup,py read

======================= *snip* =======================

======================= *snap* =======================

where /var/tmp/paluds/[...] is the folder in which -- during the
installation process -- the compilation takes place. After that, the
generated files are actually moved to /usr/[...]. It seems that I'll
need to tell UFC to include /usr/include/ rather than /var/tmp/[...].

Is the setup.py gererated by DOLFIN or UFC? Any idea how to fix this anyway?

Cheers,
Nico
