Ok :) I patch source.
Type "make rc" - the same error.
Make new copy via "fetch" - the same error.
It seems that if not exist ClusterLabs-pacemaker-Pacemaker-1.1.11-rc3.tar.gz, then download it.
Otherwise use exist archive.
Cutted log .......

Well, "make rpm" - build rpms and I create cluster.
I spent the same tests and confirmed the behavior.
crm_reoprt log here - http://send2me.ru/crmrep.tar.bz2
