Hyprlock & Hyprpaper require 'media-libs/libwebp' as a build dependency to successfully compile. As libwebp isn't kept as a dependency and isn't included in @world by default, it gets removed after running 'emerge --depclean', which will trigger portage to ask for 'emerge @preserved-rebuild'. Running 'emerge @preserved-rebuild' will not run successfully due to Hyprlock and Hyprpaper needing 'libwebp' to compile. The temporary solution is to simply add 'libwebp' to the @world. I run the live ebuild of Hyprlock and Hyprpaper, so I don't know if this affects the specific ebuild versions or not. Reproducible: Always Steps to Reproduce: 1. Install live ebuild of Hyprlock & Hyprpaper (this should fail unless libwebp was explicitly installed beforehand) 2. Remove libwebp by running 'emerge --deselect libwebp && emerge --depclean' 3. Portage will recommend 'emerge @preserved-rebuild' 4. Rebuild fails due to missing libwebp build dependency Actual Results: emerge @preserved-rebuild fails unless libwebp was manually installed, installing libwebp will remove the need for runnning 'emerge @preserved-rebuild' My computers run OpenRC and systemd, the problem occurs on both of them (hyprlock-9999 and hyprpaper-9999).
