[Santiago Vila]

Package: src:cf-python
Version: 1.3.2+dfsg1-4
Severity: serious
Tags: ftbfs

Dear maintainer:

I tried to build this package in buster with "dpkg-buildpackage -A"
but it failed:

 debian/rules build-indep
dh build-indep  --with python2,sphinxdoc --buildsystem=pybuild
   dh_update_autotools_config -i -O--buildsystem=pybuild

Configuration error:
There is a programable error in your configuration file:

--------------------------------------------------------------------------------

The above is how the build ends in my autobuilder and it's not
necessarily the relevant part.

The failure is not, however, related to using dpkg-buildpackage -A,
as it also fails in reproducible builds:

https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/cf-python.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 page for this package.

Thanks.
