[Pacemaker] libcrmcluster with ocfs2-tools-1.4.4 on Opensuse 11.2

[Roberto Giordani]

Hello,
i'm trying to build ocfs2-tools-1.4.4 on Opensuse 11.2_64bit to use
pacemaker-1.0.8-6.1
corosync-1.2.2-1.1
heartbeat-3.0.3-2,

but I need some info about this library
/* libcrmcluster*/

1)Where I can found the source?
2)Why I need openais libray if I will use corosync instead of openais?
3)Shoud I build DLM before ocfs2-tools?

Following the configure output:
