I went back and looked at all the subroutines.
2 have $pkg as arg0 (event_loop() & new_server())
7 have $conn as arg0
3 don't take args
1 starts with the line:
  shift unless ref($_[0]); # shift if first arg is package name

So maybe the entire package is actually a class.

With 1 dodgy routine: 

sub _new_client {
    my $sock = $main_socket->accept();
    my $conn = bless {
        'sock' =>  $sock,
        'state' => 'connected'
    }, $g_pkg;             #< different CLASSNAME
    my $rcvd_notification_proc =
        &$g_login_proc ($conn, $sock->peerhost(), $sock->peerport());
    if ($rcvd_notification_proc) {
        $conn->{rcvd_notification_proc} = $rcvd_notification_proc;
        my $callback = sub {_rcv($conn,0)};
        set_event_handler ($sock, "read" => $callback);
    } else {  # Login failed
        $conn->disconnect();
    }
}

It is always better to have seen your target for yourself, rather than depend upon someone else's description.
