It doesn't matter how many you have. There are only finite number of
ports and configurations. You will finish configuring at one point.
With GNU extension, one can write makefile dependencies such
that it keeps tracking and generating makefiles until all ports
to be installed are configured.
The key is how one will process /var/db/ports/* files.
I'd say it wouldn't be an easy one, though.
Ports+ doesn't do it, yet.
Check the link below if you'd like to know more. The 2nd sentence
explains the concept of doing this.
