That's macports I assume?
Also, objective C interoperates pretty well with C++ (only notable
exception is that an objc class can't inherit from a C++ class and
vice versa). If you're messing about with emacspeak (and probably
then lisp), instead of paren's, you're using brackets (same
difference? sorta except for prefix operators in lisp).
