[Click] problems with IPv6

[Daniel Pall]

I'm trying to start a xorp router (by running xorp_rtrmgr) using kernel
Click as the router's forwarding engine, and I'm running into some
difficulty with some errors related to IPv6.  I do not need IPv6 for this
particular router, so I'd be perfectly happy to turn it off completely.  My
problem is that I can't figure out if my problem is with xorp or Click.  Any
advice would be appreciated.

So, any ideas on how I turn off IPv6 completely in this context?

Thanks,
