After reflecting on this for the past week -- including numerous
iterative builds, of various related ports -- I'm now a believer in a
unified cache. My solution is to simply store it on a separate volume,
eliminating space concerns. (And in the unlikely event that
segregation is ever necessary, changing the path via
~/.macports/macports.conf works just fine.)

Thanks for all of the responses, and hope you all have a happy and
safe holiday!
