yes, it seems that you need at least 3.12.0 to compile some dependencies:
$ man Map.S
  val bindings : 'a t -> (key * 'a) list
  Since 3.12.0

we hope to distribute more portable bytecode version of OPAM for bootstrap 
later, but for now, yes we should write that in the reqs. I guess the simplest 
thing for you is to install ocaml from sources 
(http://caml.inria.fr/pub/distrib/ocaml-3.12/ocaml-3.12.0.tar.gz).
