[pkg-go] Bug#801593: Bug#801593: ratt does not find all reverse build dependencies

[Michael Stapelberg]

Thanks for the hint, I wasn’t aware of dose-ceve. When trying to run it, I
have some trouble getting it working, though:

$ dose-ceve -T debsrc -r 'golang-github-jacobsa-gcloud-dev' -G pkg
deb:///var/lib/apt/lists/ftp.ch.debian.org_debian_dists_testing_main_binary-amd64_Packages
debsrc:///var/lib/apt/lists/ftp.ch.debian.org_debian_dists_testing_main_source_Sources

The applications raised this exception : Option.No_value
$ dose-ceve --version
Build version 4.0.1

Can you explain what I’m doing wrong?
