# emerge -pqv '=media-sound/mp3diags-1.2.02-r1::gentoo' * Last emerge --sync was 70d 5h 16m 7s ago. [ebuild N ] media-sound/mp3diags-1.2.02-r1 I also bumped the ebuild to mp3diags-1.2.03 and get the same result. I will try to update world and see if it fix this issue.
please read the news items...
also, partially upgraded systems are *not supported*.
