missing .include "../../mk/x11.buildlink3.mk" in cairo and pango

["Jeremy C. Reed" <reed%reedmedia.net@localhost>]

May I add to graphics/cairo/Makefile and devel/pango/Makefile:

.include "../../mk/x11.buildlink3.mk"

?

My situation is that I have a custom X11_TYPE, like (in 
mk/x11.version.mk):
  X11_PKGSRCDIR.modular-xorg= ../../wip/modular-xorg-libs

This wip/modular-xorg-libs is a meta-package.

The difference between x11/xorg-libs/buildlink3.mk and 
wip/modular-xorg-libs/buildlink3.mk is that the former creates the 
buildlinks directly, while my meta-package just includes others.

And because the dependencies aren't recursive (if I understand correctly), 
then not all my X11 libraries are buildlinked. My fix is to simply make 
sure that mk/x11.buildlink3.mk is included in packages that use X (like 
pango and cairo).

p.s. Any volunteers to use modular-xorg? (I don't have all committed to 
wip yet.)
