We won't know which packages are doing this until you attach build logs. The preserved-rebuild messages usually say precisely what is being rebuilt against which preserved library.
Well, old images deplcean'ed in the mean while but I do have a similar situation not both at a hardened ~amd64: (1[ab].log) and at a ~amd64 : (2[ab].log)

basically, what you're doing is: install a package with USE=libav so that it forces to install libav, install mplayer (that requires ffmpeg) and see that portage correctly preserved libav's libs for the first package, then install another package with USE=libav which uninstalls ffmpeg and installs libav, which in the end unsurprisingly triggers preserve-libs for mplayer...

FWIW it happens just at both unstable boxes, the 2 stable chroot images are not affected
And furthermore - why this is closed ? Affected package should block each other, otherwise the following sequence would never finishes : 1. emerge @preserved-rebuild && end || got 1.

I reset both chroot images and added "-ffmpeg" to make.conf - so this should avoid such a situation in future, right ?
