You never initialized the Boost.MPI environment.  See the tests, but  
you're looking for something like:

mpi::environment env(argc, argv);

This basically functions like MPI_Init() plus some Boost.MPI  
initialization.  Comm_dup fails because the communicator you're trying  
to dup doesn't exist.
