OpenMPI, PETSc and petsc4py in a Mac Intel

[Ondrej Certik]

Hi,

thanks for your instructions. For those using Debian, that want to
have exactly the same configuration (petsc2.3.3 with superlu and
umfpack, openmpi, petsc4py), just add unstable into your sources.list
and do

apt-get install python-petsc4py

and that's it.
