Comment:
its `jack-devel`, its either their build system that is broken or you are missing things like `pkg-config`.

Edit: The `qjackctl` in `void-packages` still builds fine, there is nothing in void broken. You are either missing some build tools like `pkg-config` or for some reasons files are missing on your system, which you can check with `xbps-pkgdb -a`.
