I added a comment to the tracker bug to make packages work with pipewire-libjack, https://bugzilla.opensuse.org/show_bug.cgi?id=1188483. As a temporary work around. I removed pipewire-libjack and installed jack to get calf and lv2-calf to install. This solution appears to be working, but eventually calf will need to be modified to work with jack or pipewire-libjack.
