Could the buildlink3.mk including not be combined with the simplification
of the DEPENDS variable format as dicussed in the
"enforcing pkgsrc/category/$PKGBASE" thread?

E.g. the bmake infrastructure on seeing a simple "category/pkgname"
dependency could check if a buildlink3.mk file exists there and load
it (if it has not yet been loaded) etc. For me, the culprit is that instead
of declaring the dependency and later evaluating/checking all the 
dependencies,
the corresponding buildlink3.mk is immediately included with ".include".
Can't we decouple that?
