Well I've got it to work by changing priority_queue.hpp from this:

typedef parameter::parameters<optional<tag::allocator>,
                              optional<tag::compare>,
                              optional<tag::stable>
                             > priority_queue_signature;

to this:

typedef parameter::parameters<boost::parameter::optional<tag::allocator>,
                              boost::parameter::optional<tag::compare>,
                              boost::parameter::optional<tag::stable>
                             > priority_queue_signature;

I really don't know what's going on there.

Some provisional benchmark numbers coming soon...
