Right, there are problems with the coreaudio driver. Portaudio is the
only working option right now for OS X (well at least it should be
working, not tested yet). You may want to join the FluidSynth devel list
since some of this has been discussed (check the archives if you want to
read recent posts).

I'm not sure what MIDI APIs clavier supports, but since it doesn't
mention anything I imagine its probably just OSS /dev/midi. You could
get this same functionality (GUI keyboard) with Swami and more :) I've
gotten Swami to work by using fink, although it should be possible to
get it to work without it as well (using the Aqua native GTK+ port).
Using Swami also means you wouldn't necessarily need MIDI driver support
with FluidSynth since Swami drives it directly. I'm still curious what
native API (if any) OS X has for inter application MIDI. I've made some
changes to the Swami source that I haven't checked in yet, so let me
know if you are interested in giving it a try. First FluidSynth needs to
work properly of course.

Probably. If I have the time in the next week I will check it out, since
I will have access to a OS X box.
