Comment (by kencu):

 Mmm. `ocaml` builds and runs fine for me on 10.6.8.

 {{{
 $ port -v installed | grep ocaml
   ocaml @4.05.0_0 (active) platform='darwin 10' archs='x86_64'
 date='2017-12-15T14:13:57-0800'
 }}}

 I think it more a buildbot issue. On the buildbot, `ocaml` builds with
 `clang-3.4`, and thereafter, requires `clang-3.4` to run because it's
 hard-coded into the scripts.

 But there is no run dep on `clang-3.4`, and so if someone installs `ocaml`
 and tries to use it, but `clang-3.4` is not installed, `ocaml` fails.

 Looks fixable to me.
