I haven't said its not legitimate. But I guess you are trying to solve a
problem, I guess you are not doing it for self entertaining.
I was asking for the reason why you want to do it to understand 
your ultimate goal, or the problem you want to solve.
Ports/packages of gnustep are available for i386, amd64 and macppc platforms.
So I was wondering if you try to get it running on a different
platform where no ports are available, or if a port is not working for
you?

with clang, you don't install any libobjc together. You may use the
gcc libobjc, OR a different one, its up to you.

For the ports I had to use the gnustep-make flag:
--with-objc-lib-flag=-lobjc2

But that will not help if both libobjc libs, from base gcc, and
a ports gcc have the same name, or .so.VERSION extended.

gnustep makes configure --help specifies to use the flag like this:
 --with-objc-lib-flag=-l:libobjc.so.1

But that did not worked for me at all.
But maybe you can here try to use what Wolfgang proposed, with
regard to the LDFLAGS.

cheers,
Sebastian
