If you enabled FEATURE=preserved-rebuild (>=portage-2.2), then old version of libraries are NOT remove when you update. Running emerge @preserved-rebuild to rebuild all apps that depends on that lib, link with the new version, and remove the old version.

revdep-build only relink against new library. The old library might have already been removed (without portage-2.2 and FEATURE=preserved-rebuild).

明白了，謝謝
