It is possible to get up a working GNUstep system on OS X, but doing  
this is non-trivial. The issue on OS X is that we have two  
conflicting Objective C runtimes, the GNUstep one and the Apple one.  
Having both linked with your program almost instantly leads to a  
crash. Unfortunately, since OS X 10.4 Apple's CoreFoundation library  
uses Apple's Objective C runtime and a lot of open source projects  
nowadays make use of Apple specific features on OS X, which (directly  
or indirectly) use CoreFoundation.

Maybe somebody will have a look at making GNUstep work with Apple's  
Objective C runtime (i.e., an apple-gnu-gnu combo), but until then,  
you'll have to be brave (and a bit masochist :-) in order to find out  
all GNUstep dependencies that use CoreFoundation on OS X and either  
disable them during GNUstep's configuration or recompile them in a  
way such that they don't use Apple specific features.
