0 == ORTE_EPOCH_CMP(target->epoch,ORTE_EPOCH_INVALID)
when epoch is not configured as this will always return true. This caused get_route to return an error in all non-binomial routed modules, and caused all components to return an error when delete_route was called.
So protect the checks with ORTE_ENABLE_EPOCH so we get the correct behavior.
