Please remove Extra-Depends: librsvg2-dev (>= 2.54.7+dfsg-2) from gegl https://buildd.debian.org/status/package.php?p=gegl
I believe the only use of librsvg is in the one file https://salsa.debian.org/gnome-team/gegl/-/blob/debian/latest/operations/external/svg-load.c and that code is specifically designed to work with older versions of librsvg. (librsvg now uses Rust and some ports haven't been able to build it yet.) >From build logs, it looks like that Extra-Depends was added earlier this year but that file hasn't changed since 2023. Thank you, Jeremy Bícha
