Well, the other thing to try is to add an AI_ADDRCONFIG (IIRC, check the 
getaddinfo manpage) to the getaddrinfo calls and see if that fixes 
things.  I may have put that into the top of trunk netperf bits:

if you want to give those a try - hpux.connect.org.uk will have a 
subversion depot for HP-UX if you need one. (It is a subversion repository)
