All reports of package-lacks-versioned-build-depends-on-debhelper for the archive. The extended description of this tag is:
The package either doesn't declare a versioned build dependency on debhelper or does not declare a versioned build dependency on a new enough version of debhelper to satisfy the declared compatibility level.
Recommended practice is to always declare an explicit versioned dependency on debhelper equal to or greater than the compatibility level used by the package, even if the versioned dependency isn't strictly necessary. Having a versioned dependency also helps with backports to older releases and correct builds on partially updated systems.
Refer to the debhelper(7) manual page for details.
