It's this type of problem: ​http://stackoverflow.com/questions/14104298/clang-boostspirit-and-c11

So it sounds like we either have to require C++11 support (i.e. use the cxx11 1.0 portgroup), or else define BOOST_NO_VARIADIC_TEMPLATES as suggested in that stack overflow question, though that might be a global setting for boost which might negatively affect other ports that actually need variadic templates.
