You should probably be using the copy in Boost (in boost/graph/distributed 
and libs/graph_parallel); that will build with Boost's normal bjam system.

You need "using mpi ;" in your project-config.jam for the build of 
Boost.MPI to do anything.  Look at the Boost build documentation for how 
to give your MPI implementation location if Boost cannot detect it 
automatically.

It does; use ./bjam --with-graph_parallel to get it.

Look for a suspiciously small library file, most likely; you can use 
"size" or "nm" ("nm -D" for a .so file) on Linux to see if it contains any 
code.
