And even then it doesn't matter all that much because of the back-up libraries. If you follow the UPDATING instructions for when to do `portupgrade -fr' and keep you ports up to date, you shouldn't need to worry. Any residual paranoia beyond that is better satisfied by running portmanager in pristine mode IMO. > To recompile all dependants against the latest > version of a library, one has to find out which port the older > version in /usr/local/lib/compat/pkg belongs to and forcibly upgrade > all deps of that package, using `portupgrade -fr'. >
