ACL found but not expected...?

Hey guys, I've searched for this all over the net, and no one seems to have asked, so...
I've noticed that whenever I do a permissions repair in disk utility, I get these reports in the log:

(see the screenshot posted. these forums aren't letting me copy/paste the text for some reason)

I haven't done anything to make it do this. It's like this immediately after I install - every single time. Is this normal? Is there anyway to make it stop? I thought to go into terminal and manually set CHOWN/CHMOD on the offending folders, but I wasn't sure if that would screw up my whole installation. Thanks.
