error making htb example

["Michael" <michael@xxxxxxxxxxxxxxxxxxx>]

Newbie here... 
tcng version 10b

I'm just learning about htb and using tcng. I am trying to make the 
example in 
Martin A. Brown's Traffic Control with tcng and HTB HOWTO v0.5
example 2

/*
 * Simply commented example of a tcng traffic control file.
 *
 *   Martin A. Brown <mabrown@xxxxxxxxxxxxxx>
 *
 * Example:  Using class selection path.
 *
 * (If you are reading the processed output in HTML, the callouts are
 *  clickable links to the description text.)

 */

#include "fields.tc"
#include "ports.tc"

#define INTERFACE  eth0

dev INTERFACE {
    egress {

        /* In class selection path, the filters come first!  DSmark */

        class ( <$ssh> )    if tcp_sport ==  22 && ip_tos_delay == 1 ;
        class ( <$audio> )  if tcp_sport == 554 || tcp_dport == 7070 ;
        class ( <$bulk> ) \
            if tcp_sport == PORT_SSH || tcp_dport == PORT_HTTP ;
        class ( <$other> )  if 1 ;

        /* section in which we configure the qdiscs and classes */

        htb () {
            class ( rate 600kbps, ceil 600kbps ) {
                $ssh   = class ( rate  64kbps, ceil 128kbps ) { sfq; } ;
                $audio = class ( rate 128kbps, ceil 128kbps ) { sfq; } ;
                $bulk  = class ( rate 256kbps, ceil 512kbps ) { sfq; } ;
                $other = class ( rate 128kbps, ceil 384kbps ) { sfq; } ;
            }
        }
    }
}

The results indicate an error which does not mean much to me. Could 
someone explain what I might have done wrong.
