Comment (by jmroot):

 It isn't strictly a dependency since you might not even be running the X
 server on the same machine. If you want to use the native window system,
 you want gtk2 +quartz. Unfortunately the whole GTK 2 situation is kind of
 a mess, as it can't be installed for X11 and Quartz at the same time, some
 dependents rely on X11-specific functionality (hence the default variant
 being +x11), and a bunch of other dependencies also have to be built for
 the right back-end. #27990 and #60511 have a lot of discussion of the
 problem and possible solutions that could be implemented.
