Pacemaker depends on corosync.
OpenAIS is optional, but recommended,
Corosync and OpenAIS depend on Cluster Resource Agents.
Cluster Resource Agents depends on Cluster Glue.
The bottom line is that if you want Pacemaker, the best process is to
build and installall five, in this order:
Cluster Resource Agents
If it helps.. they're in alphabetical order.
