mtr issues

[Peter Hindrichs]

Good Day,

I have been using "mtr" to check the network signal from my wireless  
ISP, and it has been working fine until the other day when I updated  
my system to 10.5.3

I did an uninstall of mtr and reinstalled it, with no change here is  
what I get when I try "mtr ispnet.ca"

Freedom:~ peterhin$ mtr ispnet.ca
nodename nor servname provided, or not known: Undefined error: 0
Freedom:~ peterhin$


Now if I do a "ping"  or a "traceroute" of the same or any other  
address it works fine.

My question then is this a compatibility issue with 10.5.3 or some  
other issue.
