I was using Jeremy Yallop's simple version (same as your first
version).  I got it to work by linking it as follows:

	$(OCAMLC)                                                            \
           -I +camlp4 camlp4lib.cma                                          \
           unix.cma                                                          \
          `$(OCAMLFIND) query -r -predicates byte gettext.extract -i-format` \
          `$(OCAMLFIND) query -r -predicates byte gettext.extract -a-format` \
          `$(OCAMLFIND) query -r -predicates byte gettext.extract -o-format` \
           Camlp4Bin.cmo                                                     \
          -o $@
