Thanks for the suggestion, I've included the output below.

I've attached the traceback. Yes, I can reproduce this one at will :).

The problem only seems to occur w/ my home server. racoon on my
laptop (running -current also) has no difficulty speaking to any
of the production servers at work (running NetBSD-1.5-release +
racoon-20001211a from pkgsrc).

I have Kerberos set up though, so maybe I'll give this a try!
