To make this statement more precise, GNUstep *does* work on OS X 10.4  
and later, too, but it will not work out of the box with the  
dependencies built from MacPorts (and I guess from fink either). The  
problem is not the Apple linker per se, but rather that many of our  
dependencies nowadays depend directly or indirectly on CoreFoundation  
on OS X and, unfortunately, CoreFoundation started to depend on  
Apple's libobjc in 10.4.

To successfully build and run GNUstep on Mac OS X 10.4 and later, you  
need (at least) to configure aspell with --disable-nls (the nonls  
variant of aspell should do for MacPorts). Next, you need a freetype  
configured with --without-old-mac-fonts (unfortunately no help from  
MacPorts here and the freetype shipped with Mac OS X 10.5 will not  
work either). Apart from that, configure GNUstep-base with --disable- 
tls and GNUstep-back with --disable-glx and use either the libart  
(the default) or xlib backend. Eventually, I may have forgotten some  
other libraries in this list, but you will notice that when looking  
at the crash report being produced in ~/Library/Logs/CrashReporter.  
Look for a line containing /usr/lib/libobjc.A.dylib.

Hope this helps
