iptables install error...(for a firewall)

I'm trying to set up a firewall, or actually I think I have done it already, but I just can't use it..when I try to start, iptables cause a screw-up, and that's where my firewall falls..

so here's the basic message types I get:

/lib/modules/2.4.20-gentoo-r8/kernel/net/ipv4/netfilter/ip_tables.o: unresolved symbol nf_unregister_sockopt
/lib/modules/2.4.20-gentoo-r8/kernel/net/ipv4/netfilter/ip_tables.o: unresolved symbol nf_register_sockopt
/lib/modules/2.4.20-gentoo-r8/kernel/net/ipv4/netfilter/iptable_filter.o: unresolved symbol nf_unregister_hook
/lib/modules/2.4.20-gentoo-r8/kernel/net/ipv4/netfilter/iptable_filter.o: unresolved symbol ipt_unregister_table_R8407889c
/lib/modules/2.4.20-gentoo-r8/kernel/net/ipv4/netfilter/iptable_filter.o: unresolved symbol nf_register_hook

etc. etc. etc.

so what's going wrong? I emerged iptables packages (and some others too, which I needed) with no problems, I also had to upgrade my kernel - again, no errors - so everything should go alright. but no. iptables just screws up everything....

is it something in the compilation/upgrade of kernel or what? please, tell if you can..!

problem solved...tough I did it through updates, like this:

1) updated my kernel from 2.4.20-something to 2.4.22-something (sources first! )
2) enabled some new modules in the new kernel and compiled it
3) reboot, and firewall got runnig. yes... it just seemed like I either missed some modules (?) or then just had some weird error....don't know. good it works now.
