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.

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").

Keeping stuff in base has the disadvantage that pkgsrc doesn't really
know when they get upgraded, so if you upgrade something in base to an
incompatible version things will break unless you manually upgrade every
pkgsrc package depending on that (directly or indirectly). Nevermind
that pkgsrc might not yet have a newer version that will work with the
thing you upgraded.

I'd say that is a strong argument for a slim base (or making sure
/usr/pkg is almost completely independent of base).
