Try playing with the contents of this file and see if that matters.  
Also, try putting "#!/usr/local/bin/perl -f" on its first line.

My suspicion is that this file is passed to DOS, which will blindly try 
to execute it as if it were a .com program.  You should cause it to be 
passed to Perl instead.
