Reference to undefined global `Mysql'

I'm pretty new to ocaml, and I'm having trouble accessing my MySQL database
using it.

Here's a sample session, which shows that at least some of the ocaml-mysql
library is installed:

debian:$ ocaml
        Objective Caml version 3.09.2

# open Mysql;;
# connect defaults;;
Reference to undefined global `Mysql'


What would be the next step to debug this problem?

Thank you.

Or, if you're already in a toplevel and discover you need a module:

$ ocaml
        Objective Caml version 3.10.0

# Unix.time ();;
Reference to undefined global `Unix'
# #load "unix.cma";;
# Unix.time ();;
- : float = 1190386792.
