It may well be that the licensing conditions of any such SDK spell
end-of-line for MacOSX support since Apple is allergic to the GPL-v3.
It's conceivable that an OpenDarwin SDK without graphics support (after
all, we don't really need it, even if it means lack of supporting
platform fonts) could work instead.

So "suitable Apple SDK" does not just mean "can be made to work" but
also "is legally permitted to be made to work".
