That line is a MacPerl compatibility with MPW (Macintosh Programmer's  
Workshop), the old Mac development environment.  According the MacPerl  
book, this line allow scripts to be called directly from MPW without  
the need to call the Perl tool directly.  MacPerl knows to ignore this  
line, but Mac OS X perl does not.

I think it is safe to leave it out (and only include the appropriate  
shebang line), as if anyone is still using MPW, they are probably used  
to adding that line to Perl scripts.
