You've got carriage returns in the text of the script (the "^M" above).  
They are no considered whitespace (and in any case, IIRC, POSIX does not 
guarrentee to handle more than one argument after the command in a 
shebang ("#!") line).

You probably want to strip all the trailing carriage returns from this 
script.
