py-yaml complaints from yum
It's not a good idea to have all these repo's enabled at the same time and
without protectbase or priorities. There's likely a conflict because of
this. And it makes debugging now more complex. Try yum clean metadata and
if that doesn't help try running with a higher debug level. Maybe an
update wants to replace that package, somehow breaking the dependency.
Also, remove that i386 version.
