yum-builddep under ubuntu doesn't correctly reveal rhel macros while building fuel packages locally in chroot (fuel-main [1]) as the result wrong build dependencies are installed, for example please check the changes in spec [2], the same happens for fuel-library package [3], so we are always install rubygem-librarian-puppet-simple as build-dep.
