permission repair *always* finds stuff to 'repair' (which is the wrong
word since nothing is 'broken'), no matter what you install or do. 

all it does is go through a list of what apple thinks permissions are
supposed to be, sometimes with more than one entry for a given item on
the list, which means it will change the permissions of something and
then change it back moments later, making you think it did something,
when it really all it did was clutter up the log. 

run it twice in a row, you'll see 'problems' that are 'repaired', the
same ones each time. apple even has a tech note about that.

apple's installers are not the cause of what you're seeing, nor is it
even a problem. 

permission 'repair' is a completely pointless waste of time in all but
extremely rare scenarios, certainly not after installing apple updates.

far too many people think permission repair is some magical panacea.
it's not and it's about time it's removed, and with sip, it's actually
irrelevant because the files it would have 'fixed' can't be altered
anyway. it's even more useless now than it has been.

long ago, when macs could dual-boot to mac os 9, permissions *could* be
screwed up in 9, resulting in situations in which a 'repair' might have
helped os x, but that hasn't been an issue for 15 years because macs
haven't been able to boot os9 since then.
