Leopard Disc Permissions Corrupted, Won't Repair

Question

1. TechTool support recommend that I check disc permissions to solve a login issue. Found that aprox. 100 were corrupted and would not repair. Here is one example: Permissions differ on "System/Library/PrivateFrameworks/CoreAUC.framework/ Versions/A/CodeResources", should be -rw-r--r-- , they are lrw-r--r-- . All the aprox. 100 corrupted permissions have the same "should be -rw-r--r-- , they are lrw-r--r-- " issue.
2. I did archive and install OSX, the machine hung after accepting log in. I then installed 0SX and brought my data over from TM. I then verified permissions and they were good.
3. I next installed updates, checked permissions again. This revealed that an update or updates seem to be corrupting permissions. They again would not accept repair. What can I do to address this? The machine seems to be working fine now but am concerned that system may be at risk. Please help. Tony

We are all getting those messages from Repair Permissions that say "Permissions differ..." and end with: "-rw-r--r--, they are lrw-r--r--" or something similar, the last set of letters beginning with an "l" which means it's a symbolic link, but is probably only meaningful to programmers.
They are not errors or warnings and as Apple says in the Knowledge Base article Lyssa pointed to, they can be safely ignored.
