This patchset still doesn't work on my debian squeeze if I disabled
optimization.

  $ ./configure --enable-debug
  $ make
  $ ./sheep/sheep /store/0 -f -d
  sheep: init_store(2004) no store found
  sheep: create_cluster(1385) use corosync cluster driver as default
  sheep: create_cluster(1405) zone id = 17712138
  sheep: read_epoch(2017) failed to read epoch 0
  sheep: send_join_request(817) ip: 10.68.14.1, port: 7000

The sheep doesn't show any other log messages.  It looks like hanging.

This is also reproducible on my clean-installed debian squeeze box.

Thanks,

Kazutaka
