In the CPAN docs it, the calls it init() without any arguments. Try replacing 
Gtk2->init(\@ARGV);

with 
Gtk2->init();

Update: when calling a PACKAGE->method(), the class is passed as the first argument automatically. So that is where Usage: init(class) comes in.

Example: 
#!/usr/bin/perl
use strict;
use warnings;

Tom->init;

package Tom;
sub init(){
  print "Calling init\n";
  print "$_\n" for(@_);
}

__OUTPUT__
Calling init
Tom

- Tom
