Description of problem: perl-qpid has build dependency qpid-cpp-client-devel = 0.22 This is invalid because qpid-cpp = 0.22 shouldn't be in epel, it's part of core rhel6.
I'm not sure I understand what you mean by "invalid build dependency". perl-qpid 0.22 requires qpid-cpp-client-devel 0.22 which is available in EPEL. This is the currently released version of Qpid.
qpid-cpp-client-devel in epel6 testing must not be there! qpid-cpp-client-devel-0.14-22.el6_3 is part of base os and epel6 can never provide package in rhel6 base os.
Retired the epel package and unpushed the testing packages.
