Portable enough today. But if you want to support minor OSs like BeOS or
windows ...

... look at »perldoc perlrun«:
 #!/bin/sh
 #! -*-perl-*-
 eval 'exec perl -x -wS $0 ${1+"$@"}'
   if 0;

There is a pretty good change that /bin/sh is available on relevant
systems. But also for this solution, you cannot support all exotic
systems.
