simple Makefile problem

I have the following 3 files that I need to make dependant
$(LIB)
$(LAFFPERL)/Laff.xs
$(PREFIX)/lib/arch/auto/Laff/Laff.so

What I need makefile to do is
is Laff.xs is newer than the .so then do
perl Makefile.PL
make PREFIX=$(PREFIX)

if $(LIB) is newer the Laff.xs then
perl Makefile.PL
make PREFIX=$(PREFIX)

I'm confused about the setup.

Try something like this:

$(LAFFPERL)/Laff.xs $(PREFIX)/lib/arch/auto/Laff/Laff.so: $(LIB)
perl Makefile.PL
make PREFIX=$(PREFIX)

$(PREFIX)/lib/arch/auto/Laff/Laff.so: $(LAFFPERL)/Laff.xs
