What might have happened is python-pecan was installed prior to the cloud archive being added, then gnocchi or neutron was installed and the min version specified by the package was already satisfied, so the latest version from the cloud archive didn't get installed. I'll check the package to see what the min version is.
Can you confirm that the error goes away if you have python-pecan 1.2.1-2~cloud0 installed?
