Installing ocamlfind fails on OSX

[sgrove]

Trying to build out the workflow to something I'm used to (merlin, etc.). Not clear that this is an opam-ios issue, but it does seem to work on other switches:

Confirming on the right switch:

Is this expected right now?

[fxfactorial]

Expected since somethings will have to be compiled specially, aka this opam repository needs to provide a custom definition of ocamlfind...which of course would be high value and probably the first thing that needs to be done.

[fxfactorial]

I think I tried doing this in the beginning but for WHATEVER reason ocamlfind wants to use ncurses, so need to disable that or get around it.
