hfaxd problems on Linux

[vesdakon@algonet.se]

I am trying to set up HylaFAX on my Linux. I downloaded binaries, but...
Linux 1.2.13, Caldera 1.0
hylafax-i386-linux-v4.0pl1-1.tar.gz
As I start hfaxd I get in syslog:
Jan  6 14:51:54 josua HylaFAX[274]: /etc/netconfig: Cannot open: No such file 
or directory
Jan  6 14:51:54 josua HylaFAX[274]: getpeername: Socket operation on non-socket

Anyone have an idea?
