networkmanager-0.9.8.8 will not connect to ipv4 wired network

[John Frankish <j-frankish slb com>]

Using networkmanager-0.9.8.8 and dhcpcd-6.3.2, I am unable to connect to a wired connection eth0.

If networkmanager is stopped, dhcpcd will connect without problems.

The problem appears to be that networkmanager is stuck in a loop trying to make an ipv6 connection when the 
connection is ipv4 - ipv6 is disabled on the router.

There is another minor issue in that networkworkmanager is looking for hosts in /usr/local/etc rather than 
/etc, but adding a symlink does not resolve the issue.

Is there some way to disable ipv6 in a networkmanager conf file?

Logs below:
