In this case, updating gdbm and glew should have resulted in rebuild of reverse dependencies, but emerge fails to do so and complains about slot conflicts instead. > emerge -puDN --verbose-conflicts @world [ebuild U ] sys-kernel/linux-firmware-20200721 [20200619] [ebuild U ] dev-lang/luajit-2.0.5-r2 [2.0.5-r1] [ebuild U ] sys-devel/binutils-config-5.3.2 [5.3.1] [ebuild U ] sys-devel/gcc-config-2.3.1 [2.3] [ebuild U ] media-libs/freetype-2.10.2-r1 [2.9.1-r3] [ebuild U ] sci-libs/fftw-3.3.8-r1 [3.3.6_p2] [ebuild U ] media-fonts/fontawesome-5.14.0 [5.13.1] [ebuild U ] media-fonts/noto-20200521 [20190524] [ebuild U ] net-misc/socat-1.7.3.4 [1.7.3.2] [ebuild U ] sys-libs/gdbm-1.18.1 [1.13-r2] [ebuild U ] media-libs/audiofile-0.3.6-r4 [0.3.6-r3] [ebuild U ] sys-kernel/genkernel-4.0.10 [4.0.9-r1] [ebuild U ] sys-process/cronie-1.5.5 [1.5.4-r1] [ebuild U ] app-eselect/eselect-vi-1.2 [1.1.9] [ebuild U ] dev-lang/python-2.7.18-r1 [2.7.18] [ebuild U ] dev-texlive/texlive-formatsextra-2020-r2 [2020-r1] [ebuild U ] dev-lang/python-3.7.8-r2 [3.7.8-r1] [ebuild U ] dev-lang/python-3.8.4-r1 [3.8.3-r1] [ebuild U ] dev-python/soupsieve-2.0.1 [1.9.5] [ebuild U ] x11-libs/libdrm-2.4.102 [2.4.100] [ebuild U ] dev-python/cryptography-3.0 [2.9] [ebuild U ] x11-libs/libxkbcommon-0.10.0-r1 [0.10.0] [ebuild U ] media-libs/libglvnd-1.3.2 [1.3.1] [ebuild U ] sys-apps/portage-2.3.103 [2.3.99-r2] [ebuild U ] media-libs/glew-2.2.0 [2.1.0-r1] [ebuild U ] dev-python/arrow-0.15.8 [0.15.7] [ebuild R ] dev-python/beautifulsoup-4.8.2 [ebuild U ] x11-misc/xkeyboard-config-2.30 [2.29] [ebuild R ] dev-libs/json-c-0.14-r3 [ebuild U ] dev-libs/libgit2-1.0.1 [1.0.0-r1] [ebuild U ] app-text/xmlto-0.0.28-r3 [0.0.28-r2] [ebuild N ] dev-util/colm-0.13.0.5 [ebuild U ] x11-misc/xdg-utils-1.1.3_p20200220 [1.1.3-r1] [ebuild U ] sys-libs/libblockdev-2.24 [2.23-r1] [ebuild U ] dev-util/ragel-7.0.0.10-r2 [6.10] [ebuild U ] x11-base/xorg-server-1.20.8-r1 [1.20.8] [ebuild U ] dev-libs/libinput-1.15.6 [1.15.5] [ebuild U ] x11-libs/cairo-1.16.0-r4 [1.16.0-r3] [ebuild R ] app-emulation/qemu-5.0.0-r1 [ebuild U ] net-im/skypeforlinux-8.62.0.85 [8.62.0.83] [ebuild U ] www-client/brave-bin-1.11.101 [1.11.97] [ebuild U ] app-text/texlive-2020-r6 [2020-r5] !!!

So this is a real conflict. Sorry to clutter the bug report.
I can't reproduce this anymore.
