Ok, I tried the simplest possible example, but just didn't figure out 
where the problem is. I am on windows, mpich2 installed, all boost libs 
correctly compiled with mpi, but if I do something like

#include <boost/graph/use_mpi.hpp>
#include <boost/graph/distributed/selector.hpp>
#include <boost/graph/distributed/adjacency_list.hpp>
#include <boost/graph/distributed/mpi_process_group.hpp>

void main(){
using namespace boost;
typedef 
adjacency_list<vecS,distributedS<graph::distributed::mpi_process_group, 
vecS>, directedS>  Graph;

Graph g(4);

};

I always get linking problems like:
Error    7    error LNK2019: unresolved external symbol "void __cdecl 
boost::graph::distributed::synchronize(class 
boost::graph::distributed::mpi_process_group const &)"

boostTest2.obj

I think I have included all the necessary libs (including mpi.lib from 
mpich directory), so I still don't understand where is the problem. Does 
anyone tried distributed graph class?
