This needs to be coordinated between all the MPI implementations,
because you wouldn't be able to have LAM without the fortran lib
alternative installed together with openmpi with the fortran lib
alternative. So I'm not sure that we want to switch to that *now*.

Let's fix the only really broken thing: the mpiexec/mpirun problem in
openmpi and mpich2. After that, we can downgrade this bug and discuss
the rest of it.
