That technique is also *NOT* recommended. It works, but it can really
bog down your fax server if you carry a lot of traffic.

I hadn't taken it apart and looked: here is a copy set up for my Linux
installation, which you will need to reset the "SPOOLDIR" for.

That's really only intended for home user or incidental desk top use,
not for a fax server.

I would seriously suggest installing from source if your are running a
major service.  From what's been said on this list, some of the Red Hat
style packagings of Hylafax have cut corners and tried to make the 
install process look simpler than it needs to look to be done properly.
