Anyway, in case I missed it and he was asking how to compile a framework, 
that's really easy:

include $(GNUSTEP_MAKEFILES)/common.make

FRAMEWORK_NAME = PreferencePanes
PreferencePanes_OBJC_FILES = PreferencePanes.m OtherStuff.m YetMoreStuff.m
PreferencePanes_HEADER_FILES = PreferencePanes.h OtherStuff.h YetMoreStuff.h

include $(GNUSTEP_MAKEFILES)/framework.make

This would build our framework 'emulation' beast on GNUstep (that includes
GNU/Linux, Windows, Apple running gnu-gnu-gnu), and a standard Apple
framework on Apple Mac OS X Cocoa.
