It didn't work? That's wierd. It looks like you might not even have the correct commands installed in the correct place. Frankly, I'm not positive how serious that is, but I imagine other things would fail too. How was OSX installed on your computer, by an upgrade or as a fresh installation? You might want to consider fixing your disk permissions using Disk Utility (under Applications, Utilities, Disk Utility).

If possible, could you open a terminal by going to Applications -> Utilities, and opening 'Terminal'? Then type the following commands at the terminal's prompt:

sh
echo $PATH
exit
cd /usr
ls
ls -1 bin | wc -l

If you could email the results to me ( sberlin@limepeer.com ) that'd be very useful.

Thanks,
