[Pacemaker] solaris problem

Andreas,

thank you for sharing this link and your start script!

My goal is to make possible building those tools using more convenient way of NetBSD's pkgsrc system.
Perhaps using something like --localstatedir=${VARBASE}/cluster for both libqb, corosync and pacemaker,
and setting the appropriate permissions to /var/cluster will solve the problem.

Thanks again!
