Can't get ipset to compile - kernel-2.6.10, iptables-1.3.0...

[henry <info@intellitree.com>]

After the advice I got on using ipset for long lists of networks for ban 
lists, I set out to install it. I followed the instructions on the ipset 
webpage: Downloaded the latest kernel from kernel.org (2.6.10) 
downloaded the latest iptables (1.3.0) and downloaded the 
patch-o-matic-ng from the ipset link (patch-o-matic-ng-20041206.tar.bz2)

I ran ./runme set and it installed the patch just fine. But when I try 
and compile the kernel, this is what is happening:

I have tried compiling the ipset functions both into the kernel and as 
modules. What am I doing wrong?
