Yes, anything based on the Apple SDK seems like it will be a no-go.

However, when I looked at this last time I concluded that using
odcctools[1] we could _almost_ build a working binary.  The only
missing part is a small runtime library - literally a few hundred
lines of assembly code - which is under an old Apple license that is
incompatible with Fedora.

BTW all of the above was last discussed on this list here:

Rich.

[1] odcctools is free software, albeit with several technical and
social problems of its own.  It lacks a single upstream source, and it
only builds on 32 bit, because the code contains many 32 bit
assumptions.
