permissions repair

To properly fix issues on your Mac you either must run a repair from another disk on from the install disk. If the error is no a system files it won't be able to fix the problem. Booting from a cloned disk or and install disk and running Disk Utility should be done to completely fix problems.
That is totally false... and in fact it is *preferable* to be booted from the same volume/OS on which the permissions repairs are being done.
You may be thinking of disk repair (directory structure, catalog file, extents, etc.), because —in that case —booting from another volume is necessary, for repairs to take place. But not so with permissions.
See http://support.apple.com/kb/HT1452 (and also this User Tip by Mark Douma, for a deeper explanation).
<edit>
Having said all that . . .
Depending on the message shown, some of the reports Disk Utility produces during permissions repair these days is unfortunately misinformation (caused by a software update bug introduced in Leopard and still not sufficiently eradicated in Snow Leopard).
