$ revdep-rebuild --library '/usr/lib64/libnotify.so.1' reported "There are no dynamic links to /usr/lib64/libnotify.so.1... All done." so I deleted libnotify.so.1 Then $ revdep-rebuild reported "broken /usr/bin/notification-properties (requires libnotify.so.1)" obviously the initial library specific search is faulty, it did not find notification-properties. Reproducible: Always Steps to Reproduce: 1. emerge x11-libs/libnotify-0.7.2 2. revdep-rebuild --library '/usr/lib64/libnotify.so.1' 3. rm '/usr/lib64/libnotify.so.1' 4. revdep-rebuild Actual Results: ... emerge output excluded ... * Messages for package x11-libs/libnotify-0.7.2: * Old versions of installed libraries were detected on your system. * In order to avoid breaking packages that depend on these old libs, * the libraries are not being removed.

Starting rebuild emerge --oneshot x11-misc/notification-daemon:0 .......... Calculating dependencies... done! >>> Verifying ebuild manifests >>> Emerging (1 of 1) x11-misc/notification-daemon-0.5.0 ... emerge output excluded ... Expected Results: The first invocation of revdep-rebuild should have emerged notification-properties, rather than requiring a second run of revdep-rebuild without the --library option This problem is not specific to libnotify, I am just using it as an example. In many cases, using the --library qualifier does not detect any use of the .so, whereas after deleting the .so, it does find the dependency.
