The #! line isn't "/usr/bin/perl -c", is it? Then the args don't
match. You shouldn't try to use setuid scripts anyway, but if you
insist then you must put up with the additional security checks that
Perl imposes. Making sure that you use the same arguments when you
call perl with your script and when you invoke the script directly is
one of them.
The perlsec manpage has useful information about this. It even
includes this:
Switches On the "#!" Line
When you make a script executable, in order to make it usable
as a command, the system will pass switches to perl from the
script's #! line. Perl checks that any command line switches
given to a setuid (or setgid) script actually match the ones
set on the #! line. Some Unix and Unix-like environments
impose a one-switch limit on the #! line, so you may need to
use some� thing like `-wU' instead of `-w -U' under such
systems. (This issue should arise only in Unix or Unix-like
environments that support #! and setuid or setgid scripts.)
You really should read "man perlsec".
