I share this frustration with you. I was once told that the pain in
upgrading is due largely to a somewhat invisible difference between
installing a pre-compiled package, and building+installing a port. In
theory, if you stick to one method or the other, things will stay mostly
consistent. But if you mix them, and particularly if you update the
ports tree in the process, the end result is a bit more undefined. One
thing that I wish for is that the ports tree would branch for releases,
and that those branches would get security updates. I know that this
would involve an exponentially larger amount of effort from the ports
team, and I don't fault them for not doing it. Still, it would be nice
