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.


What we cannot speak about we must pass over in silence.
