Depends on what you want to do. If you just want to compile and run  
GNUstep programs on your OS X system, my personal recommendation is  
to use the gnustep port from MacPorts (formerly DarwinPorts). Works  
nicely here on a PowerBook for me.

Otherwise, the main problem is that GNUstep requires the GNU  
Objective-C runtime system, which is not available with Apple's gcc  
compiler. So one of the first things you want to do is to build gcc  
from the FSF with Objective C support. In addition, you need to  
compile libffi, which is part of gcc (look here
 http://lists.gnu.org/archive/html/discuss-gnustep/2006-10/ 
msg00047.html
for a note on building libffi). I think starting with these (and  
installing the other required software via MacPorts or Fink) you  
should be able to build GNUstep.
