Debian package doesn't contain a binary!

I know it's not a supported platform, but there are no contact details for it, either, so I'm unable to let them know directly. The Debian/Ubuntu .deb package you have a link to for download on your site only contains documentation, and no binary. The tar.xz on that contributor's site also contains only data files and no binary.
