mac pro 1.1 disk permissions and repair permissions question

hello everyone, i have a situation i don't understand, i recently installed a crucial m500 240 gb ssd as my os x drive, i did a clean install of os x 10.7.5 with all my updates, etc. anyway when i verify disk permissions on this drive i get several permissions that differ from what they should be, when i repair disk permissions it says disk permissions repaired yet i can verify again and all the permissions i just repaired show up again saying they differ from what they should be. this happens whether i re-verify immediately or shut down the machine and come back to it days later. can someone help me understand what's going on, and how i might fix this? thanks
