Linking library libgnustep-gui ...

etc.
The problem here is that you are linking the wrong Objective-C runtime
library. Because your programs are compiled using the -fgnu-runtime
option, they call functions within the GNU runtime, which are all those
missing symbols. The Apple runtime has similar functions but the names
are different.

Do you have a libgcc.dylib in /usr/local/lib ?
I would have thought you should be looking for the whereabouts of
libobjc.dylib.
