Back out of the upgrade, back to the previous version? The current 
_binary_ package is still the old version, so you could try to 
force-install that one (e.g. by using "portupgrade -fPP 
xf86-video-nv-2.1.11") until the port gets fixed, I guess. Haven't tried 
this (haven't upgraded yet), but it should revert your upgrade and get 
you up and running for now (but ymmv).
