That gave me a start. The circular dependency was a problem. Had to
change a few things to arrive at the following makefile which works
(tried "make -n" and all commands seem to work as expected):
############ start ############################################

SRCS:= $(filter-out %-4up.pdf,$(wildcard *.pdf))
DESTS:= $(patsubst %N.pdf,%N-4up.pdf,$(SRCS))

.SUFFIXES:
.SUFFIXES: .pdf .ps  N.ps N.pdf  N-4up.pdf N-4up.ps


default : $(DESTS)

P:
        echo $(DESTS)

%N.ps: %N.pdf
#       echo "First Step: making PS of $<"
        acroread -toPostScript $<

%N-4up.ps  : %N.ps
#       echo "Second Step: Makaing psnup of $<"
        psnup -m0.5cm -l -Pletter -pletter -4 $< > $@

%N-4up.pdf  : %N-4up.ps
#       echo "Third Step: making PDF of psnup"
        ps2pdf $<

############ end   ############################################

Defining the suffixes was important. And the restrictions on the output
filenames (*N.pdf and *N-4up.pdf) actually helped in resolving the
circular dependencies.
