Current trunk does not compile for me as follows:

./boost/graph/distributed/detail/mpi_process_group.ipp: In function ‘int boost::graph::distributed::receive(const boost::graph::distributed::mpi_process_group&, int, int, T&)’:
./boost/graph/distributed/detail/mpi_process_group.ipp:722: error: ‘stderr’ was not declared in this scope
./boost/graph/distributed/detail/mpi_process_group.ipp:724: error: there are no arguments to ‘fprintf’ that depend on a template parameter, so a declaration of ‘fprintf’ must be available
./boost/graph/distributed/detail/mpi_process_group.ipp:724: note: (if you use ‘-fpermissive’, G++ will accept your code, but allowing the use of an undeclared name is deprecated)
./boost/graph/distributed/detail/mpi_process_group.ipp: In function ‘typename boost::enable_if<boost::mpi::is_mpi_datatype<T>, std::pair<int, unsigned int> >::type boost::graph::distributed::receive(const boost::graph::distributed::mpi_process_group&, int, int, T*, size_t)’:

OK to apply the attached?
