>Description:
xfce4 packages provide many buildlink3.mk files.
Most are not needed. They provide no "build" need.

Alos the meta packages for xfce4 and xfce4-extras
use many includes of the buildlink3.mk files
instead of using DEPENDS. These are not for a "build".

The meta packages should have DEPENDS instead and specifically
require the latest versions as appropriate.

So an example problem is that xfce4-4.6.1 may end up have old
dependencies so may not really represent 4.6.1.
>How-To-Repeat:
        
>Fix:
Get rid of unneeded buildlink3.mk files.

Change XFCE4 packages to use DEPENDS to BUILD_DEPENDS
as appropriate.
