Some of it exists but I don't think its complete.

Hmm, I don't think so. Which makefile did you add this to? Are
you using the new makefile? The Makefile.pre.in file contains a
line like:
 $(LIBRARY_OBJS) $(MAINOBJ): $(PYTHON_HEADERS)
but newmodule.o not in LIBRARY_OBJS. By default its not compiled
by make but with distutils. If you add newmodule to Setup then a
line like:
 Modules/newmodule.o: $(PYTHON_HEADERS)
would do the trick. I think I will add a line like:
 $(MODOBJS): $(PYTHON_HEADERS)
to fix the problem.
I could easily restore the mkdep target but my feeling right now
that explicitly including the header dependencies is better.
What do you think?
