That's exactly what will happen with 1.8.0. port commands will upgrade
dependencies before building the requested port. If you don't want that
behavior (e.g. upgrading something like qt4-mac may take hours) you can
use 'port -n'.

Version dependencies could reduce the number of unnecessary/unwanted
upgrades in cases where you can build against the installed version of a
dependency and upgrade later.
