normally speaking, Sage uses python3 it finds (assuming it's not to old etc) And we regularly get reports from users who unwittingly trigger Sage's build of python3, and it breaks. (I advocate for removing the ability to build python3 from sage, but well, we don't have a consensus on this it seems) > `/home/grhkm/git/sage/local/var/lib/sage/venv-python3.12/lib/python3.12/site-packages/setuptools/...` > which contains the setuptools package used for building.
