Dear maintainer:

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

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

dh build-indep --buildsystem=ruby --with ruby
   dh_update_autotools_config -i -O--buildsystem=ruby

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

https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/ruby-bourne.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.
