On OS X, I don't use X11 at all. And I think we should not ask users to install X11 when programs work fine with native graphics.

At this moment, libepoxy will either build with native OS X graphics or with modular X11. I recommend adding an 'x11' option, turned on for all platforms except Darwin and move the OPSYS==Darwin condition to options.mk.

Kind regards,
