I am currently working on some scripts to do that, but they aren't in good
shape yet. To see which ports a specific ports depends on ("upstream" in your case?),
you can run "make" with 
* all-depends-list
* build-depends-list
* package-depends-list
* run-depends-list
as a target.

Send me an email if you need anwsers for specific ports now and I can
test my scripts.

Cheers,
