Actually this applies to both SUSE and openSUSE (all versions) since this is
most likely a packaging problem and packages for all distros are packaged the
same time by OBS.

Since I first encountered the bug, I have since found a workaround that works,
I'll describe that first...

Workaround:
Instead of trying to install from either software.opensuse.org or the repos,
Install by downloading the package from the OBS and installing
https://build.opensuse.org/package/show?project=Cloud%3AOpenStack%3AKilo&package=openstack-neutron

NOTE: The above workaround suggests that current OBS builds for Kilo have not
been pushed to the repos. I encountered a similar problem with the Controller
pattern and will see if going directly to the OBS solves that, too.

The following stdout with reported errors when attempting to install from the
openSUSE 13.2 and SUSE 12 repos:

System: openSUSE LEAP 42.1 (although I doubt the error has anything to do with
the OS version)
 Repository: openSUSE (also tried SUSE)
