Comment:
@ericonr speaking about possible breakage of `zlib-ng`, if you haven't removed `zlib` after installing `zlib-ng`, you can just run `xbps-alternatives -s zlib`. Even if you've removed `zlib` there's `xbps-static`. As the last resort there's an option to `chroot` into your system via Void installation media and then copy `libz.so` from it.
