`which perl` -x $0 $*
That's a useless use of backticks. which will only find something which is in the PATH, and then shell can find it as well, so you can just rephrase that as perl -x $0 $* That reminds me - perlrun has the following snippet: 
#!/bin/sh
eval 'exec perl -S $0 ${1+"$@"}'
  if $running_under_some_shell;

# regular perl code follows here

If you really want, you can also put switches for Perl at the end of the shebang line if it looks like so: #!/bin/sh -- # -*- perl -*- -wT
