bulk builds incompatible with changes

[John Klos <john%klos.com@localhost>]

Hi,

Does anyone have any suggestions about what to do about updates to the 
pkgsrc tree when running bulk builds? Stopping a bulk build and rescanning 
from scratch is really not ideal, particularly on slower systems.

Ideally, I'd like if there was a straightforward way to do a new scan on a 
fast system, then merge the updated things in to the build for the slower 
system. I've done this manually, but it's definitely not straightforward.
