I have no clue about Windows, but when Boost cannot find my MPI
compiler wrapper under Linux, I just append this line to the
"project-config.jam" file in the root directory of Boost:

    using mpi : /path/to/mpicxx ;

Of course, you need to replace /path/to/mpicxx above with the path to
your "mpic++.exe" executable (or whatever the MPI compiler wrapper is
called in Windows).

Best regards,
Riccardo
