Some get removed with postinstall obsolete, some don't.  I've never
really figured out what's going on, but occasionally I'll explode
the sets to a temporary directory, and do a find/diff dance to
identify leftover stuff.

..and then it usually turns out that I forgot to recompile any
local programs that still needed them :)
