I'm not sure about the version, but I'm using the current version from
the hg repository at http://hg.code.sf.net/p/octave/fem-fenics.  Is this
ok or should I download a particular release archive from somewhere?

With

  export CPPFLAGS="-I/usr/include/eigen3 $(mpicxx -showme:compile)"

it configures fine and builds some files, but fails later on with the
attached error message.  The first few errors are these:

mkoctfile -I/usr/include/eigen3 -I/usr/lib/openmpi/include
-I/usr/lib/openmpi/include/openmpi -pthread -c plot_mesh.cc  -o
plot_mesh.o -I.

I've installed libdolfin1.3-dev from the FEniCS Ubuntu repository,
presumably that's the correct library -- or not?  Is this an error
related to the interface changes in libdolfin, or is it a completely
different problem with my system?

Yours,
Daniel
