2) is taken directly from the example on the Boost.MPI website, right? But 
that's just an example, for the case when you're using LAM/MPI. It won't 
work in your case because you're using Open MPI. It will probably look 
more like this:

using mpi : : <find-shared-library>openmpio <find-shared-library>openmpi++
             <find-shared-library>mpi ;

You'll have to consult the Open MPI documentation to find out what exactly 
to fill out there.

I'm not very familiar with MPI compiler wrappers (or with MPI in general, 
so if anyone more informed can help please do so), but if your MPI headers 
are not in your CPPPATH then yes, you should probably specify the Open MPI 
include path in your Jamfile. Like this:

project : requirements <include>C:/wherever/you/put/openMPI ;

You can find the entire Boost.Build documentation here:
