Okay I recompiled things without my changes so I could list the error I 
get. When compiling in the gui directory it stops here:

Making all in Tools...

There are a lot more undefined symbols after this but you get the idea. 
My work around was to change these lines of Makefile.preamble:


# Additional library directories the linker should search
ADDITIONAL_LIB_DIRS += -L../Source/$(GNUSTEP_OBJ_DIR) 
-L../Model/$(GNUSTEP_OBJ_DIR)

# Additional libraries when linking tools
make_services_TOOL_LIBS +=
gpbs_TOOL_LIBS += -lgnustep-gui $(SYSTEM_LIBS)
set_show_service_TOOL_LIBS += -lgnustep-gui $(SYSTEM_LIBS) 
gopen_TOOL_LIBS += -lgnustep-gui $(SYSTEM_LIBS)

to


# Additional library directories the linker should search
ADDITIONAL_LIB_DIRS += -L../Source/$(GNUSTEP_OBJ_DIR) 
-L../Model/$(GNUSTEP_OBJ_DIR) $(ADDITIONAL_DEPENDS) -L/sw/lib -lgmp 
-lxslt -lxml2 -lz -lpthread -liconv -lm -lffi -ldl  -lz

# Additional libraries when linking tools
make_services_TOOL_LIBS += -lgmp -lxslt -L/sw/lib -lxml2 -lz -lpthread 
-L/sw/lib -liconv -lm -lffi -ldl  -lz
gpbs_TOOL_LIBS += -lgnustep-gui $(SYSTEM_LIBS)
set_show_service_TOOL_LIBS += -lgnustep-gui $(SYSTEM_LIBS) 
gopen_TOOL_LIBS += -lgnustep-gui $(SYSTEM_LIBS)

When I did this it compiled fine. But as you can see it is a pain to 
have to include all those additional libs every time I want to link a tool.

Thanks for this suggestion. I was trying to find the command to print 
out the make info. Eventually I started using 'make -N' :)

I get a bus error when I use -f.  I've recompiled with debugging symbols 
and I am going to try to figure out what causes this. BTW when it links 
gdnc I get a warning about multiple symbols definitions for 
NSDistributedNotificationCenterDummy. Is this normal?

Thanks for your help. I really want to get this running so I can start 
writing some portable apps on my mac.
