Do you havea list of packages which overzrite something, respectively
do you have a list of files which are overwriten?
If we just talk about the nvidia lib, installing the mesa and nvidia

/usr/local/lib/<port>-gl/" to rc.conf could be an option.
What we cannot speak about we must pass over in silence.
