With GNU-make-isms, you can do that with something like (untested):

%-front.pov: %.coords
	coords2front $< > $@

%-top.pov: %.coords
	coords2top $< > $@

%.pgm: %.pov:
	povray +I$<

%.jpg: %-front.pgm %-top.pgm
	montage ... $^ $@

Then "make -j 4 pretty.jpg ugly.jpg" should do the necessary work to build
two images using up to 4 processes in parallel.
