Hey Kjell,
argus-, which is the official version, has fixes for ICMP, but the more recent developers version has specific bug fixes for ICMPv6 that you should be of interest to you.  


These versions have been really stable and you should consider them to be the current versions at this point.

The source port should represent the ICMP type value, and the destination port should represent the ICMP code value.  At least that is the intended behavior of the tools.
