Looks like there might be a few minimal config changes to make, as trying a simple build throws problems with include (malloc.h not found)
Also usb seems to be needed. Could be interesting.

Bit more digging, and it looks like the libftdi that is included won't build on mac OS: there's 0.18 available which should. I'll have a play
