I can confirm that existing binaries of GNUstep works on Tiger. I can  
also confirm that GNUstep doesn't work on Tiger :-)
-- the compilation is ok,... well you need to get a libobjc as usual,  
but with some little tweak it compiles with Apple's gcc. 
The problem is with loading dynamic code, that doesn't work. And as  
GNUstep relies on bundles to load the GNUstep gui backend... same  
problem with FSF's gcc..

So in short, at the moment GNUstep doesn't install/work properly on  
Tiger. But my previously compiled version worked (although compiling  
doesn't work anymore, so it's not really practical appart for  
deploying..)
