I got bug report #591159 complaining that twidge wouldn't build because
hoauth depends on libghc6-dataenc-dev-0.13.0.2-fff02, but that package
isn't available. Indeed, that libghc6-hoauth-dev binary package does
depend on that specific package, but the source package just build-deps
Is there is need to get some binNMUs for packages that were built
against some older dataenc-dev? I'm a little unsure what specifically
was happening there.
