Yeah, that works! Here's my Gentoo deviation from the above:

AddDefaultCharset utf-8

CamlLoad /usr/lib/ocaml/nums.cma
CamlLoad /usr/lib/ocaml/site-packages/extlib/extLib.cma
CamlLoad /usr/lib/ocaml/site-packages/netstring/netstring.cma
CamlLoad /usr/lib/ocaml/site-packages/postgres/postgres.cma
CamlLoad /usr/lib/ocaml/dbi/dbi.cma
CamlLoad /usr/lib/ocaml/dbi/dbi_postgres.cmo
CamlLoad /usr/lib/ocaml/site-packages/calendar/calendar.cma
CamlLoad /var/www/localhost/htdocs/cocan/html/_bin/cocanwiki.cma

Let me play with cocanwiki for a few days. Then I'll write the necessary 
ebuilds for Gentoo:
   o ocamldbi
   o ocaml-postgres
   o ocaml-calendar
   o cocanwiki

and submit patches for those ocamlfind issues in the process. Can't wait 
to see what this
thing can do!
