error compiling ipt_connlimit.c

Is connlimit from patch-o-matic-ng-20041114 incompatible with the kernel version 2.6.9? I´m getting this error:

net/ipv4/netfilter/ipt_connlimit.c: In function `count_them':
net/ipv4/netfilter/ipt_connlimit.c:100: error: structure has no member named infos' net/ipv4/netfilter/ipt_connlimit.c:107: error: structure has no member named infos' make[3]: *** [net/ipv4/netfilter/ipt_connlimit.o] Error 1
make[2]: *** [net/ipv4/netfilter] Error 2
make[1]: *** [net/ipv4] Error 2
make: *** [net] Error 2

I think it´s because of the changing in the structures in the conntrack as of 2.6.9. Any ideas to solve the problem?
