    If libraries with incompatible license would require to be linked, it
    means "nothing" in the sense of "there is nothing we can offer for
    MacOSX".
    
We can offer sources and a build recipe; we cannot distribute the software, but 
we can distribute the sources, if I understand the GPL correctly.

Apple would let somebody who own a Mac  link against the SDK and distribute an 
executable, since it is designed to run on Apple hardware.

I don't think the GPL would let us distribute a binary, since the LilyPond 
organization can't get the sources to the SDK.
