All reports of missing-python-build-dependency for the archive. The extended description of this tag is:

The package appears to use Python as part of its build process in debian/rules but doesn't depend on Python.

Normally, packages that use Python as part of the build process should build-depend on one of python, python-all, python-dev, or python-all-dev depending on whether they support multiple versions of Python and whether they're building modules or only using Python as part of the package build process. Packages that depend on a specific version of Python may build-depend on the appropriate pythonX.Y or pythonX.Y-dev package instead.

Refer to Debian Policy Manual section 4.2 (Package relationships) for details.
