   I believe the way to go is to merge aalib-x11/buildlink.mk into
aalib/buildlink.mk.  They are basically the same, so all that needs
changing is the dependency in the new, unified aalib/buildlink.mk to:

BUILDLINK_DEPENDS.aalib?= aalib{,-x11}>=1.4.0.4

   Then aalib-x11/buildlink.mk can be retired. This way, packages
only have to include aalib/buildlink.mk for either aalib or aalib-x11.
Packages that depend on a specific (X11 or non-X11) version can override
this dependency.
