What OS X / macOS version? Boost should build with whatever the default C++
ABI is, which will be pre-C++11 on 10.8 and older; see
https://trac.macports.org/wiki/LibcxxOnOlderSystems for how to change this
(it is much, much more involved than just rebuilding boost --- changing C++
ABI is not trivial at all, and it is all or nothing --- otherwise nothing
can trust any other libraries to be compatible).
