Repair Disk Permissions - ACL found but...

Question

Suddenly Repair Disk Permissions gives an exceptionally long list of "ACL found but not expected on xxxxxxxx" and apparently is unable to carry out repairs as each run of the "repair" brings up the same long list. Additionally, the reason I ignited the disk permissions repairs was that my PowerBook Pro suddenly appeared extremely slow - taking up to 3 hours to update a single application. I'd appreciate any feedback on correcting  this ongoing issue.
Thanks - Earl

Thanks so much for your advise, Linc, and sorry for the delay in getting back - things have ben pretty hectic since. I've now done as you suggested but rather than trying to find the log for the date the issue started (scrolling through what seems like miles and miles of lines of data) I've copied and am posting here a more recent section of the log taken while attempting to install an update to OS X 10.10.2 for the past 20 hours. Any help would be highly appreciated.
