Technically correct. OTOH, an empty build-dependency field means the package is not using debhelper for its build, but instead has some grotesque by-hand debian/rules file. So this error will only ever affect packages that are not using modern best-practice packaging. I'm sure I could easily find a volunteer to submit a patch switching runit to use dh(1), to make this issue go away for you. > if so where should wanna-build bugs be filed (since wanna-build is not > currently in Debian)? does anyone have a simple testcase to see if the > assertion in the comment about Dpkg::Deps is also true? There is a buildd.debian.org virtual package in the BTS: http://bugs.debian.org/buildd.debian.org Cheers, -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
