Is this an old system or a fresh one?
6-8 months old.
What package manager are you using?
sys-apps/portage-2.3.20 as shown in emerge --info
emerge -av1 libarchive libwebp seams to have fixed it qcheck results for the two above packages show MD5 mismatches so I recompiled them and re ran unsymlink-lib --analyze and am now good to continue.
Yeah, maybe you hit some short-lived bug in those packages or something. Can't really figure out why it was wrong like that.
