GNUSTEP_SYSTEM_ROOT is gone, what replaces it?

[David Chisnall]

Hello,

I am trying to update the GNUstep ports on FreeBSD, but Preferences.app now 
doesn’t build because the new version of GNUstep-Make now errors for any 
Makefile that references GNUSTEP_SYSTEM_ROOT.  The documentation doesn’t tell 
me anything useful for migration.  I have tried this patch, based on reading 
the GNUstep makefiles:

--- Modules/Keyboard/GNUmakefile.orig   2002-02-12 04:49:55 UTC
+++ Modules/Keyboard/GNUmakefile
@@ -3,7 +3,7 @@ include $(GNUSTEP_MAKEFILES)/common.make

+BUNDLE_INSTALL_DIR=    $(GNUSTEP_SYSTEM_LIBRARY)/Preferences
 
 Keyboard_RESOURCE_FILES= \
        Keyboard.gorm

But now Keyboard.prefs isn’t installed.  Please could someone who understands 
GNUstep Make help?  This is currently blocking committing the updates to all of 
the GNUstep ports.
