Is Rmpi packaged somehow or are you getting it from CRAN?

The web site http://www.stats.uwo.ca/faculty/yu/Rmpi/ suggests it  
should work with either LAM-MPI or OpenMPI or even MPICH2

Have you installed the mpi-selector RPM and set it up? This will set  
up LD_LIBRARY_PATH to the selected MPI version. But I don't know if it  
will fix your issue.
