[boost] How do I configure MPI?

I'm trying out Boost.Build.  I used to get warnings like:

//===================================
warning: Graph library does not contain optional GraphML reader.
note: to enable GraphML support, set EXPAT_INCLUDE and EXPAT_LIBPATH  
to the
note: directories containing the Expat headers and libraries,  
respectively.
warning: skipping optional Message Passing Interface (MPI) library.
note: to enable MPI support, add "using mpi ;" to user-config.jam.
note: to suppress this message, pass "--without-mpi" to bjam.
note: otherwise, you can safely ignore this message.
Building Boost.Regex with the optional Unicode/ICU support disabled.
Please refer to the Boost.Regex documentation for more information
(don't panic: this is a strictly optional feature).
//===================================

I added a "using mpi ;" line, and now I'm getting errors like:

//===================================
MPI auto-detection failed: unknown wrapper compiler mpic++
Please report this error to the Boost mailing list: http://www.boost.org
You will need to manually configure MPI support.
//===================================

So, how do I configure MPI support?  Do I have to set up GraphML  
support first?
