Well, w/o having seen the code, this sounds like a bit of a hack :) Also I'm not sure what problem you're solving. Pkgsrc already has working package dependencies. The serious issue is with handling upgrades.

yup. possibly so.

Problem solving: installing a box that does X, and specifying a box
  that does 'X' simply.

e.g.: my desktop is 80%


and webdev is 80%


therefore 'workstation' ==

require desktop
require webdev

and I'm done - and I don't care if package 'foo' switched to latest-desktop-technology-blah v4.6d in the meantime, and I don't
have to track it in the makefiles.

also makes it easy to make tools that automate system builds, etc..

Eh, to do this properly you'd have to upgrade all packages depending on your 'base' packages and all packages depending on those packages and so on ("transitive closure").

I'd only really do this for 'core' things - like a DNS server, MTA, etc.

(those pesky types of things that keep getting moved out of base)

these tend to be highly contested leaf-nodes, which don't really
have dependancies - aka things that 'used to be' part of the OS.

I personally blow away the entire system at each release - and
don't really do much in the middle (effectively 'upgrading all packages') . Test box gets test packages - if I get the time to do it. Though I'm adressing my workflow as I get back up to speed from where I was ~2y ago..
