starting up ipv6 on redhat linux

[Antonio Querubin]

I'm trying to get IPv6 working on a Redhat 6.1 system for the first time.  
The kernel and modules have been recompiled with ipv6 and ipip tunneling
enabled.  I've also recompiled the latest net-tools package with ipv6
enabled.  However, whenever I try to install the ipv6 module (ie. modprobe
ipv6) I receive a bunch of error messages.  These all look like ipv4
functions that should already be in the kernel or a module.  Maybe I've
left some other kernel/module option off that should also be enabled.  
Can somebody point me in the right direction?  I've already gone through
the FAQs but maybe I'm just overlooking something obvious.
