As far as I understand it, the permission repair process needs the 
package receipts in order to find out what are the permissions of each 
file in the system. It is possible that there are old files that 
haven't been deleted when upgrading, and thus when repairing 
permissions, Disk Utility wouldn't know what to do with those (for 
example, the KeyCaps application doesn't exist under Panther anymore, 
but will stay in your system if its OS was upgraded from Jaguar to 
Panther). Therefore, to be completely safe, it might be a good idea to 
keep all those Receipts, especially since they each use up at most 1 MB 
or less of space. On the other hand, maybe the Permission Repair 
program ignores old packages anyways... Ciao,

                Renaud

P.S. I just saw the following:

but I'm not sure if this information is trustworthy.
