Yes, this was a problem with Boost 1.33.1 and previous. The CVS  
version of Boost has an extra overload of write_graphviz that accepts  
a vertex id property map parameter. You can probably use the latest  
graphviz.hpp directly from CVS:

        http://www.boost-consulting.com/boost/boost/graph/graphviz.hpp

This change will be present in Boost 1.34.0.

        Cheers,
