I've been thinking about this myself.  In my case I didn't want lang/gcc*
to get rebuilt to many times since thats my pksrc comiler on solaris.  I
started on implementing just this but got sidetracked.

agreed.  Thats something I wish I'd done in the first place.

Any thoughts about the initial bootstrapping of these pkgs?  It seems that once
you do the initial build of them (along with any dependencies) you may need to
use pkg_info to get their dependencies as pkgsrc diverges from there.
