Hi!
Thanks for your explanation.
Don't you think it would be good if the x11/xorg-libraries port checks
whether x11/nvidia-driver is installed and updates it in the
post-install target?
Is there a feature in the ports system that handles these issues?
Otherwise one could perhaps mention this in pkg-message or in UPDATING?
It's not really intuitive
