However, I’m using MP and the g++ from mp when trying to build.  And yes, I rebuilt ports, from scratch, when I upgraded (clean install) to Mavericks.

Oh, and yes, I did a +universal when I installed gcc49 and gcc48.  And if it matters, I installed gcc49 (with libgcc) before gcc48.  When I tried gcc48 then gcc49 I got an error about libgcc, but doing it the other way works.

Shouldn't that be '#include <cctype>' since you're compiling as C++?
