Hey Alan,

Thanks for looking into this.  I've applied a patch to ob-ocaml.el which
should handle the two different tuareg execution functions.

I would recommend evaluating first org-babel-execute:ocaml then possibly
org-babel-prep-session:ocaml in "edebug" mode.  This can be done by
running `eval-defun' on these functions with a prefix argument, or
equivalently doing "M-: (eval-defun t)".

I would guess this is due to a change in tuareg mode.
