Please always include the full build.log and emerge --info. I assume that it's fixed now, as of: commit ad03267bb46c64806b666576b37266446a7e9918 Author: Michał Górny <mgorny@gentoo.org> Date: Sun Apr 13 04:18:37 2025 +0200 dev-python/pillow: Bump to 11.2.1 Signed-off-by: Michał Górny <mgorny@gentoo.org> commit 4d3e08e4179c48797e10e30d7293ac96f9b7b70b Author: Patrick Lauer <patrick@gentoo.org> Date: Sun Apr 13 04:40:34 2025 +0000 dev-python/pillow: Fix avif useflag handling Was accidentally using wrong useflag for enable/disable Signed-off-by: Patrick Lauer <patrick@gentoo.org>
Yes, it's now fixed by 4d3e08e4179c48797e10e30d7293ac96f9b7b70b
