Doesn't look like I have traceroute, but traceroute6 which uses IPV6.  When I 
use it, I get 

arthur@rodney:~ $ traceroute6 www.google.com
traceroute: unknown host www.google.com


When I use tracepath, I get 

rthur@rodney:~ $ tracepath www.google.com
 1:  192.168.1.65 (192.168.1.65)                            1.277ms pmtu 1500

The tracepath man page says (in compating to traceroute)

The situation with tracepath is
worse, because commercial IP routers do not return  enough  information
in  icmp  error  messages.  Probably, it will change, when they will be
updated.  For now it uses Van Jacobson's trick, sweeping a range of UDP
ports to maintain trace history.
