On attempting to use the `gentoo/stage3:nomultilib-20250505` image with `gentoo/portage:20250505`, with --platform linux/arm64, many of the most basic dev-python packages (stuff that is already installed on stage3) will require a rebuild to account for the switch to python 3.13. This is not the case when the TARGETARCH is amd64, so I believe this is a gap in how the tarballs or images are built between arches. Reproducible: Always Steps to Reproduce: Run ``` docker build - <<< 'FROM gentoo/portage:20250505 AS portage FROM --platform=linux/amd64 gentoo/stage3:nomultilib-20250505 WORKDIR /build RUN --mount=type=bind,from=portage,src=/var/db/repos/gentoo,dst=/var/db/repos/gentoo \ emerge -v dev-python/installer' ``` for the most basic repro, or use this compose.yml for something more exploratory: ``` services: gentoo: image: gentoo/stage3:nomultilib-20250505 volumes: - cache-distfiles:/var/cache/distfiles - cache-edb:/var/cache/edb - type: image source: gentoo/portage:20250505 target: /var/db/repos/gentoo read_only: true image: # subpath must be relative subpath: var/db/repos/gentoo volumes: cache-distfiles: cache-edb: ``` and run `docker compose run -ti gentoo emerge -pv dev-python/installer`. Actual Results: ``` # emerge -pv dev-python/installer These are the packages that would be merged, in order: Calculating dependencies... done! Dependency resolution took 0.70 s (backtrack: 1/20). [ebuild R ] dev-python/installer-0.7.0::gentoo USE="-test" PYTHON_TARGETS="python3_13* (-pypy3_11) -python3_11 -python3_12* (-python3_13t) (-pypy3%) (-python3_10%)" 907 KiB Total: 1 package (1 reinstall), Size of downloads: 907 KiB !!!

However, it is also possible that conflicting dependencies exist such that they are impossible to satisfy simultaneously. If such a conflict exists in the dependencies of two different packages, then those packages can not be installed simultaneously. You may want to try a larger value of the --backtrack option, such as --backtrack=30, in order to see if that will solve this conflict automatically. ``` Expected Results: I'd expect dev-python/installer to already be installed, and to (pretend/) reinstall with no USE/PYTHON_TARGETS changes.

I realized after the fact this is probably an issue with the tarball and not the docker image per se, but I only have the means to test this in docker at the moment, so if this ticket needs to be moved, I hope you can do that.
I think the stage builds are pending, they got stuck on some other issues that are fixed now.
