It was a while ago. The project has been on hold for a month or so, but
IIRC, the problem was that the control deamons (dlm_controld.pcmk and
ocfs2_controld.pcmk) had some dependancies on openais, and wouldn't compile.

Do you think it would be worthwhile waiting for the new version? It's my
understanding that I should be able to upgrade a running cluster from
openais 0.80.5 to 1.0.0+. How difficult is that likely to be?
