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

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?
You'll need an MPI implementation. See: http://www.boost.org/doc/libs/1_35_0/doc/html/mpi/getting_started.html
Do I have to set up GraphML support first?
No, this is unrelated. - Doug
