Thanks for forging ahead with trying to get things running.  It sounds 
like you've gotten all the prerequisites going just fine.  But I would 
guess that the reason why you are running into problems is that you are 
working with a 2.6 kernel.  To date, there hasn't been a PerfSuite release 
meant for use with anything but 2.4.

That's the bad news, but the good news is that an updated release should 
be coming out shortly, and that is being developed against 2.6.  So I'd 
advise you to wait until available, and try again.

The different behavior when run as a normal user and as root is a little 
worrisome, though, as there should be no need to have any special 
privileges to run psrun (unless you are working with things like SUID 
binaries).

The "hardware event not available" error message means pretty much what it 
says - that the event listed in the configuration file is not available on 
that platform.  There have been a few updates to PAPI over the past 
several months and a new release out just today, for which events listed 
in the configuration files will be checked against the current PAPI 
support before the next PerfSuite release.

Thanks much for the report,
Rick
