It could be "if using 10.9 or later, don't depend on external ruby".

For the rest ... many packages use +python27, +python33, ... or
+gcc47, +gcc48, ...

So the port could provide +ruby19, +ruby20, +ruby21 and then the
installation would rewrite all the ruby scripts in the software to use
exactly the intended ruby version from hardcoded location. The port
could check whether any of those rubies is already installed on the
system and use the most appropriate variant. Or simply use +ruby21 and
let the user pick a different one.
