Couple of more points:

I am attempting to rebuild dolfin 0.9.0 after switching the defaults in
debian (as suggested by Harish, i.e. update-alternatives to openmpi),
however build fails with the following error (oddly enough build did not
fail before this change !! ).

scons: *** [dolfin/swig/cpp_wrap.os] Error 1
scons: building terminated because of errors.

Looks like either -Werror flag will need to be done away with or cpp_wrap.cc
may need to be fixed to elminate warnings. Unfortunately I am not familiar
with scons to fix this.

Also I noticed though building dolfin requires MPI there is no explicit
build dependency in the Build-Depends line of the debian/control file. It is
listed as :

Build-Depends: debhelper (>= 5), python (>=2.5), python-central (>= 0.5.6),
scons, swig (>= 1.3.36), python-dev, python-numpy, libgts-dev, libxml2-dev,
libboost-dev, libsuitesparse-dev, petsc2.3.3-dev, ufc (>= 1.1)

Note: (Only change made by me are replacing python-all by python (>=2.5) and
swig (>=1.3.37) by swig (>=1.3.36) for reasons discussed in this thread.

This line must also have "libopenmpi-dev" in it or better "libopenmpi-dev |
libmpich1.0-dev" if fenics is indeed compatible with both openmpi and mpich
and requires MPI (as suggested by enableMPI=1 in debian/rules)!.

A minor point - VERSION=0.8.1 (in debian/rules) it should be 0.9.0 but it
doesn't seem to be used.

ATTN Johannes :

Please do let me know if you need any information regarding the debian
packages installed on my system to replicate the problems in this thread. It
is a pretty standard Debian/Lenny install. You could email me directly if
you prefer.
