(usagi-users 01417) error building kernel with USAGI

[Lamia Chaffai <lamia@xxxxxx>]

Dear  usagi list members,
I've tried to compile kernel (linux RH 7.1) with the usagi kit 3.1 (linux24)
but I got the following error:

net/network.o: In function 'ip-tunnel_xmit':
net/network.o(.text+0x42cf1): undefined reference to 'icmpv6_send'
net/network.o(.data+0x3860): undefined reference to 'ipip6_rcv'
net/network.o(.data+0x3864): undefined reference to ''ipip6_err'
make: ***  [vmlinux] Error 1

Did any of you meet this problem before? 
Thank you  for your help
