 Hi,

 First of all, this seems to be strongly related to this ticket: #38984.

 On Mavericks (with a fresh install of MacPorts, not a plain upgrade), I
 have the following behavior which turns out to be very alike the one I had
 reported in the aforementioned ticket, except that this time GCC is
 broken, but Clang is not:

 {{{

Comment:

 You cannot mix C++ software compiled with libstdc++ (i.e. anything
 compiled with FSF GCC, i.e. your foo.cc) with C++ software compiled with
 libc++ (i.e. boost and most other ports compiled using clang, llvm-gcc, or
 Apple GCC on Mavericks or later). Compile your foo.cc with clang instead
 of FSF GCC.
