The issue linked above is: VERIFY python-psphere Package "Vendor" is not "Red Hat, Inc." on SRPMS noarch: Jonathan Kinred <jonathan.kinred> This is not an internally developed package. Jonathan Kinred is the primary upstream developer. Is it acceptable to leave him as the Vendor?
OK. Eck clarified that the field needs to be removed entirely. I have done so and brewed as 0.1-5.
