The return type of in_edges() is a pair of in_edge_iterator's, not
vertex_iterator's. So you should do something like this instead:

boost::graph_traits<Graph>::in_edge_iterator ei;

for (ei=in_edges(v,g).first;
       ei != in_edges(v.g).second;
      ++ei){

Hope that helps,
Jeremy

P.S. Also I recommend using boost::tie in the for loop, as is done
  in most of the graph examples.
