The parameters passed to the Getopt::Long::GetOptions() function are different to the Getopt::Std::getopts() function. One way to call GetOptions() is to pass a hash with the keys specifying each option, and the values specifying a reference to a variable that will be set. Here is an example based on your code:

our ( $opt_d,$opt_h,$opt_l,$opt_L,$opt_i,$opt_o,$opt_P,$opt_p,
  $opt_q,$opt_r,$opt_v,$opt_c,$opt_help );
GetOptions(
    'd'      => \$opt_d,
    'h'      => \$opt_h,
    'l'      => \$opt_l,
    'L'      => \$opt_L,
    'i'      => \$opt_i,
    'o=s'    => \$opt_s,
    'P=s'    => \$opt_P,
    'p'      => \$opt_p,
    'q'      => \$opt_q,
    'r'      => \$opt_r,
    'v=s'    => \$opt_v,
    'c'      => \$opt_c,
    'help|?' => \$opt_help,
);

Since your code has a lot of options, you may want to look at storing the options in a hash, rather than individual variables. Check out the Getopt::Long manpage for more info.
