Generally this doesn't cause a problem as when portupgrade upgrades a
library through a major revision, it puts a copy of the old library
into a compatibility directory. 

Applications that depend on updated libraries get version-bumped when
the library major version gets changed, so just keeping your ports
up-to-date is all you normally need to make sure everything is using
the latest libraries.
