Just a quick note here, I noticed several days ago that I missed
updating the perl code to also handle versioned Provides (so
dpkg-checkbuilddeps will not work on those yet). I've got this fixed
locally pending a bit more testing, but it will make it into 1.17.14,
to be released RSN (i.e. days).

Thanks,
