From http://www.gnustep.org/information/machines_toc.html :
 1.3 Darwin/PowerPC

 Currently tested on Darwin 6.x, 7.x

 Recommended compiler
gcc 3.3.2. Older versions will not compile on Darwin.

 Default compiler has unknown problems. Use the GNU runtime. Download  
the gcc compiler and configure it with --enable-threads=posix.

"Default compiler" means Apple GCC. "Use the GNU runtime. Download the  
gcc compiler" means download FSF GCC and compiles it, FSF GCC includes  
the GNU runtime which GNUstep is relying on… :-)

Well I admit it is not very clear. The fact is GNUstep (base, gui and  
back) cannot be built on Mac OS X with Apple GCC, except for  
gnustep-make and gnustep-base extensions. Apple GCC is bundled with the  
NeXT runtime for Objective-C which is different from the GNU runtime  
used by GNUstep, but even if you install the GNU runtime and you  
specify to GCC to use it for Objective-C code, it won't work.
… otherwise FSF GCC bundles the GNU runtime unlike Apple GCC. In the  
future the possibility to specify which runtime we want to use when we  
compile either with Apple or FSF GCC could be restored but it is not  
the case currently.

I have updated the 'Machines' documentation one month ago to make  
things more clear  
http://savannah.gnu.org/cgi-bin/viewcvs/gnustep/gnustep/core/make/ 
GNUstep-HOWTO?rev=1.33&content-type=text/vnd.viewcvs-markup but it  
hasn't been reflected on the gnustep.org web pages, it needs to be  
done… :-/

For a complete GNUstep installation on Mac OS X, read  
/gnustep/core/make/Document/README.Darwin, it is fairly detailed.
Important : you need GNUstep recent cvs version, because the last  
release of the Apple developer tools this fall introduced a linker  
update which makes impossible to link latest released GNUstep packages  
(The problem is corrected in GNUstep cvs).

I hope it helps.
