We don't want beta libs and Erlang doesn't need it.
Also disabled installation of erlang docs as we just delete them, we need to make the delete step optional.
OS X provides OpenSSL already. Thus policy dictates this formula be keg-only.
In fact policy dictates we shouldn't even provide this beta version in master tree. So I'm not sure if it should even stay. Supposedly erlang needs it. I think this is false.
