We are interesting experimenting with Boost.MPI testing as part of our nightly testing. We have had several attempts at enabling Boost.MPI that always fail with the message:

===============MPI Auto-configuration===============
MPI auto-detection failed: unknown wrapper compiler /usr/bin/mpCC
Please report this error to the Boost mailing list: http://www.boost.org
You will need to manually configure MPI support.
MPI launcher: /usr/bin/mpiexec -np
====================================================

bjam --debug-configuration gives the same message. Our user-config.jam has the following line:
using mpi : /usr/bin/mpCC : : /usr/bin/mpiexec ;

Is this supposed to work? Is there something else that we are missing?
