The new libexif installs the following files in /usr/lib/ /usr/lib/libexif.so -> libexif.so.12.2.0 /usr/lib/libexif.so.12 -> libexif.so.12.2.0 /usr/lib/libexif.so.12.2.0 but these packages try to load libexif.so.10 : [ebuild R ] media-libs/libgphoto2-2.2.1-r1 [ebuild R ] media-gfx/gphoto2-2.2.0 [ebuild R ] media-gfx/gimp-2.2.14 [ebuild R ] media-gfx/gthumb-2.8.1 [ebuild R ] media-gfx/eog-2.18.1 [ebuild R ] gnome-extra/gnome-screensaver-2.18.1 [ebuild R ] gnome-base/nautilus-2.18.1 [ebuild R ] gnome-extra/nautilus-cd-burner-2.18.1 Creating a new symlink does the trick for me, but reemerging might be more appropriate Reproducible: Always Steps to Reproduce: 1. update to latest libexif Actual Results: some packages do not find libexif.so.10
