Yes - you're right - the current Makefile.conf, does not include
APPLIBS in the $(LIBS) variable that it passes to the linker for
applications built against a binary distribution (this differed from
the source only distribution). This would appear to be a bug. The
appropriate lines in Makefile.conf are now:

ifeq ($(LDCONFIG),bin)
LIBS= $(APPLIBS) $(DISTOBJ) -lobjc -lX11 -lm $(OTHERLIBS) $(SYSDEPLIBS)
else
SWARMLIBS= -lanalysis -lsimtools -ltkobjc -lactivity -lrandom -lobjectbase 
-lcollections -ldefobj
LIBS= $(APPLIBS) $(SWARMLIBS) $(SYSLIBS) -lobjc -lX11 -lm $(OTHERLIBS) 
$(SYSDEPLIBS)
endif

Duly noted and fixed for the next release - thanks!
