Bug#898077: lintian: False positive in missing-build-dependency-for-dh-addon, python package

[Ross Gammon <rossgammon@mail.dk>]

Package: lintian
Version: 2.5.55
Severity: normal

Dear Maintainer,

When building laditools, the missing-build-dependency-for-dh-addon lintian
warning is received because scour is not a build dependency when the scour dh
addon is used in debian/rules.

However, python-scour is a build dependency and pulls in the scour package.

Lintian should perhaps check of there is a python package that meets the
dependency requirement? Or allow e.g. "*scour"?

Regards,

Ross
