Perhaps it's a little overkill, but what I usually do when I
perform upgrades like this, is to move /usr/local out of the
way (along with /var/db/pkg), and remove any X/KDE/QT stuff
in /tmp, /var/.., etc.  Then I install (portupdate -NR) everything
from scratch.  If something goes wrong, I just have to move the
original /usr/local back until I work out the problems.
