Package: src:kombu

Dear maintainer:

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

(The above is just how the build ends and not necessarily the most relevant part)

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

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

where you can get a full build log if you need it.

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.

Thanks.
