It appears that Red Hat 9's IPv6 support is completely broken.  I think 
the simplest thing to do about this is to make an explicit check for RH9 
in the configure script and turn off IPv6 support if we detect it.  Red 
Hat EOLed RH9 years ago, so I don't think investing much effort in it is 

Does this seem reasonable?
