Title: Use system ruby for macvim

Force ruby interpreter to be /usr/bin/ruby for macvim, which segfaults with 1.9.x. I am unsure if there is a use case to use a different ruby, but it was not configurable before, save by manipulating whichever ruby was first in your path during compile.

Only tested on lion, unfortunately, as I'm not in a place to test other systems.
