Varnish 4.1.3 (RPM rhel6) not listening on all interfaces

Hi all,

I've been upgrading Varnish to 4.1.3 using an RPM

All is good, except of Varnish cannot be configured to listen on all
interfaces via sysconfig file?! I read the docs and they claim that the
sysconfig works as before - EG, :80 will make Varnish listen on port 80
on all interfaces. However, I cannot achieve this! Varnish errors out

Starting Varnish Cache: Error: Cannot open socket: :80: Address
family not supported by protocol

Currently I *must* specify all the IPs I want Varnish to listen to on
in the sysconfig file.

This is particulary annoying when trying to automate the config with a
mix of physical and virtual IPs..

I'm assuming I'm doing smth wrong, anybody has any suggestions?
