Just loading ExtLib should fix this.  You need the following lines
before you load cocanwiki.cma:

CamlLoad /usr/share/mod_caml/registry.cmo
CamlLoad /usr/lib/ocaml/3.08.3/nums.cma
CamlLoad /usr/lib/ocaml/3.08.3/extlib/extLib.cma
CamlLoad /usr/lib/ocaml/3.08.3/netstring/netstring.cma
CamlLoad /usr/lib/ocaml/3.08.3/postgres/postgres.cma
CamlLoad /usr/lib/ocaml/3.08.3/dbi/dbi.cma
CamlLoad /usr/lib/ocaml/3.08.3/dbi/dbi_postgres.cmo
CamlLoad /usr/lib/ocaml/3.08.3/calendar/calendar.cma

(Actually I'm not sure if _all_ of those are required for COCANWIKI,
but certainly many of them are ...)

Yes, that's a mistake.  I need to fix the Makefile to use ocamlfind
ocamlc ...
