I am not a user of OpenMPI, but it seems the MPI library path is not in
your LD_LIBRARY_PATH. In my opinion you should not be able to run an MPI
application with your setup.
Since I don't know what kind of shell you are using, I cannot give
precise help. But for the BASH you would have to add a line in the
