 boost 1.44.0 deletes a capability used by some existing ports, such as
 wesnoth; see [ticket:26449 MacPorts ticket 26449]. See
 [https://svn.boost.org/trac/boost/ticket/4460 Boost ticket 4460] for why
 this was removed from boost, and how to get it back for now until software
 like wesnoth is updated to no longer use that capability.
