upgrading ports/packages

[Gary Kline]

	Is there a set of switches that portupgrade will use to upgrade
	(from src) _only_ the ports that need rebuilding?   I'm guessing
	"not" because it's either -arp or else portupgrade exits without
	doing anything!

	My aim is to build every package just once here (700+Mhz) and 
	scp and pkg_add the pacakges to my slower boxen?  But even after 
	using pkgdb -F, the pkg_version -vIL'=" results are unchanged.

	thanks for any clues!

	gary
