Yes, I'm on ubuntu 10.04. I first tried sudo php runme.php nand, but that didn't work, so I did "sudo su".
Well, this question may not be that significant since I was able to proceed by commenting some lines out in runme.php. But, I imagine some others may run into the same issue. For reference, this is what I did:
Comment out line 43 and 44 of runme.php like so
# if ($_ENV["USER"] != 'root')
# die("You must run this as root\n");
