GNUStep runs on top of X11.  OSX normal GUI is a totally different beast 
(Cocoa on display PDF).  Both use the NS API.  Emacs can not mix two different 
GUIs.  Just because the libs are there doesn't mean it doesn't hurt to link in 
them.  The event handling, window handling, and all other stuff are compleatly 
different.  You don't expect X11 libs to work on W32 by just linking them in 
to the executble do you?

The libs are there, but shall not be linked in unless GNUStep, and thereby 
X11, is used.
