that's OK, the Irix is redundant. there's only one unix OS with version
5.3 that it could possibly be.
Here's the rc.ratz file that configures lo:0 on other unix OS's.
It will be in the next version of configure. It's just a shell
script wrapped around the posting from ratz sometime late last year.
I never got to post it. Sorry you had to go dig it all up from the
archives when I had it on my disk.
(Since you've got yours running, this is for anyone else on the list
who hasn't yet).
