I was using this branch.
I also tried running the tool on ubuntu lucid (2.6.32-based).

Didn't you have to at least fixup the sched event names to drop :r?
Once you have the perf.data file, how do you dump it?

I tried:
- perf sched trace -> error
- perf sched replay -> error
- perf script sched-migration  -> hangs
- perf report -D
