[Nat] boost::bind defines _1 (etc.) placeholders that you must use with
boost::bind(). boost::lambda defines _1 (etc.) placeholders that you
must use with boost::lambda::bind(). Sadly, the two sets of placeholders
are incompatible. Might that be your problem? Try explicitly qualifying
your placeholder:

... boost::bind::_1 ...

If that works, then adjust your using clauses appropriately.
