[Opa] 14.1 Hello External Binding Tutorial

I'm following the hello binding tutorial :
http://doc.opalang.org/index.html#_bindings_with_other_languages

so I can get to work building bindings with PubNub, but the generated
plugin from following the steps seems to have a problem.

1.14.3 and 1.14.4 work fine. I build the plugin and can view it with
the opa-plugin-browser. But when I attempt:

$ opa plugin.opp hello_bindings.opa

it files with:

File "link_hello_bindings_001.ml", line 242, characters 40-72:
Error: Unbound module PluginMLRuntime
make: *** [link_hello_bindings_001.cmx] Error 2
error during ocaml compilation -- the command was :
make --makefile=MakefileLinking -W MakefileLinking -j 7 cmxa -s
you can see compilation logs in
/Users/tristan/Devel/opa_binding_test/_build/hello_bindings/compilation.log

Also, that log file does not exist. And in the documentation it actually
has a typo and says "$ opa plugin.opp hell_bindings.opa"

But those are just details.

More importantly does anyone know what the error is saying? Is there maybe
something wrong in the code copied into the tutorial I am using?

Thanks,
Tristan
