Boost templates produce the worst to read error messages gcc can offer.
With a closer look, most noise is centered around a single line:
1394: return vertexLessThan(
      boost::target(a.toEdge(), g), boost::target(b.toEdge(), g));
in the context of a reverse_graph.

Another error in property_map gives, thankfully, this explanation: no known
conversion for argument 1 from 'const
boost::detail::reverse_graph_edge_descriptor<boost::detail::edge_desc_impl<boost::bidirectional_tag,
long unsigned int> >' to 'const key_type& {aka const
boost::detail::edge_desc_impl<boost::bidirectional_tag, long unsigned int>&}'

In the changelog for boost Graph 1.48, I see 
"Changed edge_descriptor type for reverse_graph to a new data type to avoid
ambiguities with the edge_descriptor of the underlying graph. "
So I assume this is the cause: source incompatible changes in the new release.
