The two prerequisites do not exist as targets in the makefile, that's 
right. But they do exist as readable files in the same directory.

I tried the following and the rule gets applied:

-------------------------------------------------
.PHONY: pfps.eps pfpscut.eps

pfps.eps:

pfpscut.eps:

%.dvi: %.tex pfps.eps pfpscut.eps
        latex $<

%.pdf: %.dvi
        dvipdf $<
-------------------------------------------------
% make -n fps.pdf
latex fps.tex
dvipdf fps.dvi
rm fps.dvi


It's strange, that the rule doesn't apply if the prerequisites just exist 
as files in the directory.

Now that this worked, i moved on towards the real example and the rule 
again does not get applied:

-------------------------------------------------
.PHONY: 1.gp

1.gp:

%.eps: 1.gp
        gnuplot $<

%.dvi: %.tex pfps.eps pfpscut.eps
        latex $<

%.pdf: %.dvi
        dvipdf $<
-------------------------------------------------
% make -n fps.pdf
tex fps.tex
dvipdf fps.dvi
rm fps.dvi

The two EPS prerequisites should be creatable by the rule %.eps but make 
fails to apply it. Please find below the output of make -n -d

Of course, the file "fps.tex" exists as well. In fact I provide an ls 
output of the directory. Please find it at the bottom of this mail.
