Too late for "-%s" option

(X) The #! line (or local equivalent) in a Perl script contains the -M, -m or -C option.

In the case of -M and -m, this is an error because those options are not intended for use inside scripts. Use the use pragma instead.

The -C option only works if it is specified on the command line as well (with the same sequence of letters or numbers following). Either specify this option on the command line, or, if your system supports it, make your script executable and run it directly instead of passing it to perl.
