Dear maintainer:

I tried to build this package in buster but it failed:

The build was made in my autobuilder with "dpkg-buildpackage -A"
but it also fails here:

https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/networking-l2gw.html

If this is really a bug in one of the build-depends, please use reassign and affects,
so that this is still visible in the BTS web page for this package.

Unfortunately, I can't compare build logs with the official ones at
buildd.debian.org because they do not exist:

https://buildd.debian.org/status/package.php?p=networking%2dl2gw

Please reconsider uploading in source-only form.

Thanks.
