How hard would it be to implement a "smart-update" target?

Basically, "smart-update" would check its dependencies' (and their
dependencies') versions (installed versus pkgsrc); only if different then
deinstall. If it is ran in a pkgsrc directory already up-to-date, then it
will say so.

Any ideas? (Anything I should look at in bsd.pkg.mk before I try
implementing this?)
