It looks like it was probably broken in Debian unstable at the time that we
froze, and the nature of universe is that it doesn't receive the QA
attention that main does.

"tacky" or not, many of the uninstallable packages in universe are due to
other packages which fail to build, and if they were fixed, these packages
would become installable.  There's no need to remove them when the
underlying problem is usually easily fixable if someone investigates it.
