New comment by ericonr on void-packages repository https://github.com/void-linux/void-packages/pull/25413#issuecomment-706393792 Comment: You need to rebuild `mlt` as well (because of `mlt-python3` - it installs files in `/usr/lib/python3.8` directly :c ). There are probably a few other missing packages as well. For a branch with resolved conflicts, see https://github.com/ericonr/void-packages/tree/python-3.9
