After installing qt511-qtbase and qt511-qtmultimedia from macports
on my OSX 10.11 system (there is a qt513 but it requires OSX 10.12),
I can build the Qt interface with hints/macosx10.10-qt by overriding
QTDIR. It doesn't actually need the extra CFLAGS, and without those
I wonder whether the multimedia package is needed either, but I've
left them in. I have changed them to not be passed to the C sources
though, just the C++ ones.
I haven't tried combining with X11 or adding curses.
