ah, I am wanting to keep using the bulk build environment to do package
builds from within that so that I force myself to keep a record of the
packages I want in /etc/mk.conf - so that when I do want to rebuild the
lot it all Just Works ...

The problem is that if I build a package in an ad-hoc manner using make
package in the same chroot environment (it's the only package build
environment I have) things don't seem to be smart enough to do the bulk
build trick of installing package dependancies from binary packages if
they're available and so it remakes them ...

Worse, this causes the bulk build to rebuild them all again because the
timestamps get out of sync ...

Ah, that's probably what I want - thanks ...

Fair enough - I plan on running a normal bulk build after a CVS update,
which should sort out that problem ...
