OCaml and Opam: unbound module Core

Please follow the steps in the Real World OCaml Wiki - Installation Instructions.

Under Setting up and using utop, the instructions state that you should add:

#use "topfind";;
#thread;;
#camlp4o;;
#require "core.top";;
#require "core.syntax";;

to your ~/.ocamlinit file.

So I jumped the gun a bit. I forgot to add some items to my ~/.ocamlinit file. Specifically I forgot to add

#use "topfind"
#camlp4o
#thread
#require "core.top"
#require "core.syntax"

as mentioned in Chapter 1. D'oh!
