In agents, a simple "./configure && make" leads to:

[...]

In pacemaker, I build without openais-devel installed (don't want to
build against OpenAIS 0.80.3 found on CentOS); Heartbeat and Glue are
built and installed from current tip. "./configure && make" leads to:

[...]

As said, all of this is on CentOS 5.3.
