Hmmm... I get the suspicious feeling you guys are *nix rather than Mac OS X. OS X isn't case sensitive as far as I can tell. I ran it both with correct capitalisation and without. What you see in my first post, is what I get!!!! (and, as far as I can tell, I'm following your instructions to the letter). I'm running in a so-called admin account (accounts and permissions have made OS X so complicated unless you become a programming expert).

Is there an account greater than admin, and, if so, how do I change my OS to such a level?

PS to Mac users out there: OS X 10.0.3 is still distinctly a beta OS... if you want a responsive computer, don't bother upgrading until OS X 10.1 or 10.5 is out... right now it's a *nix lover's paradise since it marries a sort-of-Ok interface (better than any of the Linux GUI's I've seen) with the innards of a UNIX).
