MarsSeed [1] filed a deletion request for libviperfx-nonfree-bin [2]: Broken VCS package from 2018; no one complained about it. (Cannot be packaged and does not follow Arch guidelines. Does not declare its dependencies and its name should end with -git.) Development also discontinued in repo since 2018. Therefore I recommend to delete this abandoned and wrong VCS package.
