Not quite. It's more complicated because of the fact that at least three
different implementations (LAM/MPI, MPICH and MPICH2, OpenMPI) provide
/usr/lib/libmpi.so and there is no soname encoded.

Also note that it isn't strictly incompatible. Some users of Open MPI that
were built agains 1.2.* continue to work under 1.3.

I am kindly requesting those who have a reverse dependency on Open MPI (aka
libopenmpi1) to rebuild their package against the version in unstable.  

Let me/us know if you have other questions.

My thanks to Christophe and Ondrej for dealing with paraview. One more down,
couple more to go...

Thanks, Dirk
