Hi,

At lines 329 and 330 make IntraPacketLatency and IntraPacketLatencyRev just 
PacketLatency and PacketLatencyRev respectively. That should be the only 
change you need after that. I have updated the code in the maddash trunk to 
print a better error message in this case since a NullPointerException isn't 
very helpful. This change will be included next time we cut an RPM. Thanks 
for reporting it.

Andy
