This package has a binary package dependency in ceilometer-common on
dpkg-dev for dpkg-vendor, which is rather unusual/unexpected. This can be accomplished by running dpkg-vendor at build-time, and using a debhelper #TOKEN# on the maintscripts, and passing that value via dh_installdeb
with an override for example:
Or even w/o an override by exporting DPKG_VENDOR and then using #ENV.DPKG_VENDOR# in the maintscripts. Then the dpkg-dev dependency
can be dropped from ceilometer-common.
This has been entangling this package with dpkg's testing migration for
several Debian releases via its autopkgtests.
