[SOLVED] netcfg fails to add IPv6 gateway

Question

After updating the (~2-month backlog of) packages on an Arch Linux VPS, I can no longer get netcfg to bring up eth0 with an IPv6 gateway.  However, if I bring up eth0 manually, it works...
[root@inception ~]# ifconfig

I don't know if I borked something during the package upgrades -- there were those couple announced ones that required minor manual intervention.  Any ideas?

(I've changed the IP addresses.)
