[Teaching] Getting OCaml set up on a mac

[Yaron Minsky]

Also, I can't seem to install depext, but the reason doesn't make sense:

Kalessin:~ yminsky2$ opam install depext
[ERROR] depext is not available because your system doesn't comply
with opam-version >= "4.02".
Kalessin:~ yminsky2$ opam --version
1.2.0

I'm running the latest opam available from homebrew.
