Error "ACL found but not expected on..." when doing repair permissions.

I am getting an error on Disk Utility, Repair permissions. I was having some problems with permissions and sought and received help through forum regarding changing my userid password through Lion Repair (Control R, etc.) After finishing that ordeal, rebooting, etc. everything seems fine and works well, perhaps slightly slow. I decided to go into Disk Utility again and I repeatedly get the following errors...

"ACL found but not expected on “usr/sbin/system_profiler”

Repaired “usr/sbin/system_profiler”

ACL found but not expected on “usr/sbin/systemsetup”

Repaired “usr/sbin/systemsetup”

ACL found but not expected on “usr/sbin/traceroute”

Repaired “usr/sbin/traceroute”

After about a 20-25 minute repair process, I clear the report ,exit disk utility, reboot the computer and I still get the same report. Disk verify shows the hard drive to be functioning well. What is the source of these errors and is there a solution.

Thanks,
