The python-kombu package does not have sufficient version constraints to match the requirements of the python modules. This can prevent the python-kombu package from being loaded. I am working on python-kombu-2.5.16-1.el7 What I notice is, it does not have any version constraints for the python-amqp package requirement: # rpm -q --requires python-kombu python(abi) = 2.7 python-amqp python-anyjson rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(FileDigests) <= 4.6.0-1 rpmlib(PartialHardlinkSets) <= 4.0.4-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1 rpmlib(PayloadIsXz) <= 5.2-1 # rpm -q --conflicts python-kombu (nothing) However, the packaged requires.txt has more specific constraints on amqp and anyjson: # cat /usr/lib/python2.7/site-packages/kombu-2.5.16-py2.7.egg-info/requires.txt anyjson>=0.3.3 amqp>=1.0.13,<1.1.0 This becomes a problem because EPEL-7 also packages python-amqp=1.4.5 and this causes problems when kombu loads. I think the RPM spec file for kombu needs updating to add version ranges on the dependency for python-amqp. From the output above it also needs version criteria for python-anyjson.
