This would work OK for runtime dependencies but handling build-time
only dependencies would need some careful thought.  Whilst it might be
reasonable to automatically remove gcc-ooo after installing
Openoffice.org, I probably wouldn't want autoconf, automake, imake etc
deleted immediately after building something that needed them.

They can't be treated totally as runtime dependencies because you don't
need (or want) them installed if you install a package (rather than
building a port).

Agreed.
