I upgraded to a new snapshot.

This demonstrates that I don't understand the mechanism by which these upgrade decisions are made then. How can pkg_add determine that a given package was built against newer libraries if there is nothing in the package header (+CONTENTS) indicating such? I assumed this would manifest itself in the package signature in some way, since pkg_add is clearly making an upgrade decision here. Or there is of course the possibility that there *is* some information there that I'm overlooking.

Multiple times. My problem is that the documentation appears to be written for a user of OpenBSD, not necessarily someone trying to fully grok the inner workings of exactly how the pkg_* tools work. I've tried reading the perl directly, but I haven't found anything that seemed like a smoking gun. I guess what I want to know is, what *exactly* is pkg_add doing/comparing to determine that an upgrade is needed?

No PKG_PATH. /etc/installurl is ftp3. Unchanged since my install ~8 months ago.
