Ok, sounds way easier though still difficult ;-)

This is wrong. Only the gcc driver is gcc 2.95.2, the ObjC compiler is
still the old, 2.7.x based NeXT compiler.
Stan Shebs of Apple is working on porting up the NeXT changes to a
recent gcc, hopefully this will work out sometime in the future.

Hm, currently GNUstep on Darwin has quite some pitfalls (and indeed I
know  no one who has successfully done that)

I don't think ffcall runs on PowerPC. I'm not sure whether gstep-base
depends on it, I don't think so. I have doubts that gstep-base will
compile with the nx runtime out of the box.
You won't need dgs and gnustep-guile. Openssl should come with Darwin
and libxml should be easy to port and use.

No, this isn't possible with plain Darwin because of the missing
Foundation library, it's possible with MacOSX.
