It's a while ago that I was using Boost.MPI. But if auto-detection fails,  
you could pass MPI-related options explicitly. There is this remark in the  
MPI Jamfile:

# If your MPI implementation does not have a wrapper compiler, or the MPI
# auto-detection code does not work with your MPI's wrapper compiler,
# you can pass MPI-related options explicitly via the second parameter to  
the
# mpi module:
#
#    using mpi : : <find-shared-library>lammpio  
<find-shared-library>lammpi++
#                  <find-shared-library>mpi <find-shared-library>lam
#                  <find-shared-library>dl ;

HTH,
Boris
