Yep, it's normal. Are you running 10.5.1? I believe that update is supposed to reduce the number SUID "error" messages from nine to one, but I think there was some issue where that only happened if you manually downloaded and installed the update instead of getting it through Software Update. Could be wrong about that though...haven't been paying that close of attention to it since I'm still a Tiger user. Regardless, it's nothing to worry about.
