New comment by tornaria on void-packages repository https://github.com/void-linux/void-packages/pull/45086#issuecomment-1644786290 Comment: scipy needs patching to build with pybind 2.11 (or maybe `--skip-dependency-check` since all the patches are about relaxing dependencies (cython, numpy, and now pybind11). Note that in their main branch they have relaxed the upper bound for cython and pybind11 (they still fix numpy to a particular version). See: https://github.com/scipy/scipy/blob/main/pyproject.toml
