Note that there is a '\r' character at the end of the #! line.
And that's the cause of the problem. The kernel is scanning for
'\n' and when it finds the (unix) end-of-line character it then
tries to exec the program "/bin/sh\r" and fails.
Was the original script created on a windoze box perhaps? Or was
a different method of getting a \r used? :)
