Comment (by ballapete):

 A few more C header are needed:

 {{{
 gdkquartz.h -> gdk
 {gdkquartzcursor.h,gdkquartzdevice-core.h,gdkquartzdevicemanager-
 core.h,gdkquartzdisplay.h,gdkquartzdisplaymanager.h,gdkquartzdnd.h,gdkquartzkeys.h,gdkquartzscreen.h,gdkquartzutils.h,gdkquartzvisual.h,gdkquartzwindow.h}
 -> gdk/quartz
 }}}

 Then the port built.

 The missing files are available here:
