[CentOS] yum upgrade of an older 6.1

Major Changes)

Matahari is now obsoleted, but in 6.1, had a dependency on
qpid-cpp-server and qpid-cpp-client which wanted updates.  A quick
Google shows many others seeing this problem.  I think if you run yum
with the --obsoletes flag you may get more information.  IMHO you need
a human to decide when/if to remove the obsoleted packages and proceed
with the update.
