I had a similar problem.

As it turns out, Boost.Polygon already uses a level of indirection
internally. You can specialize boost_polygon_traits_general (instead of
boost_polygon_traits).

This is undocumented, but it was the only way I found to get it working.

I would argue this is a bug, or at least a deficiency. Not sure if the
right fix is to change the documentation or the implementation.
