This suggests that somehow Trilinos was unable to find your MPI library at the location indicated in your configuration.  Note that all the "undefined reference" errors refer either to MPI functions or to OpenMPI's implementation of MPI functions (e.g., "ompi_mpi_comm_world").  Are you able to build a simple MPI program on the cluster that does not use Trilinos?  If not, then your configuration probably isn't pointing to the right location for MPI.  If so, then please come back to us with the Makefile that works for the non-Trilinos MPI program, and your MPI configuration for Trilinos, and we'll try to help out :-)

Thanks!
