/usr/lib/ocaml/pcre should not be listed by 'ocaml-ldconf -l' because
PCRE's .so is now installed in /usr/lib/ocaml/stublibs (well, this is
true on Woody, on sid it's now installed in
/usr/lib/ocaml/3.06/stublibs) which as you can test is listed by
'ocaml-ldconf -l'.

Try this easier way, just tested on a woody box which use the same
apt-gettable repository you are using:
$ ledit ocaml
Objective Caml version 3.06
# #use "topfind";;
Findlib has been successfully loaded. Additional directives:
#require "package";; to load a package
#list;; to list the available packages
#camlp4o;; to load camlp4 (standard syntax)
#camlp4r;; to load camlp4 (revised syntax)
Topfind.reset();; to force that packages will be reloaded
- : unit = ()
# #require "pcre";;
Loading /usr/lib/ocaml/pcre/pcre.cma
# open Pcre;;
This is easier because the first '#use' statement loads findlib's stuff
which is able to understand information stored in META files like 'home'
directory for each libraries and additional linking options. Having
access to this kind of information '#require' statement need fewer
information from the user ...
Cheers.
