I added -linkpkg to my `ocamlfind` string in scripts/Makefile, hoping it 
would solve the
linking problem by compiling the interfaces in, but now I get this:

# make all install
make -C scripts all
make[1]: Entering directory `/usr/local/src/ocaml/cocanwiki-1.3.12/scripts'
ocamlfind ocamlc -w s -I +apache -package pcre -I +dbi -package extlib

ocamlfind ocamlc -w s -I +apache -package pcre -I +dbi -package extlib

Hmmm.... netstring.cgi conflicts with apache.cgi. How do I get around that?
