i guess the answer to all of your questions is: makefile.dependencies 
has to my knowledge not been used for years!
it just get's created (or not), but it is never included into 
build-process, so it would be better to just remove it.

btw, the gnu make manual suggest to use one dependency makefile per 
sourcefile, instead of one general makefile.depend.

something like:


<snip>

-include $(SOURCES:.c=.d)
endif

%.d: %.c
         @set -e; rm -f $@; \
          $(CC) $(MAKEDEP_FLAGS) $(CFLAGS) $< > $@.$$$$; \
          sed 's,\($*\)\.o[ :]*,\1.o $@ : ,g' < $@.$$$$ > $@; \
          rm -f $@.$$$$


</snip>

(this example is copied from the Gem sources, so it might not work out 
of the box for pd, but you should get the idea)
