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
ones into subdirectories and asking to add (or adding
automatically/optionally) ldconfig_paths="$ldconfig_paths
/usr/local/lib/<port>-gl/" to rc.conf could be an option.
