I am not familiar with scons, but the idea I had was to employ an autoconf-like support in the build system to try to build a sample program that uses boost.mpi, and to define a preprocessor symbol named e.g. HAVE_BOOST_WITH_MPI if that sample builds well. Perhaps some scons expert can tell if it is possible to do with scons?

FWIW, Boost.Build has just recently got that kind of support IIRC.
