Well, if you compiled your own kernel, you'll have to go back to the
config stage and add in the options for iptables.  Looking at "make
menuconfig" for kernel 2.6.12, you'd go to the menus
Device Drivers -->
    Networking Support -->
        Networking Options -->
           [*] Network Packet Filtering (replaces ipchains) -->
And then beyond that you configure lots of modules under "IP:
Netfilter Configuration".

If you're using a kernel from your Linux distribution, I'd be
surprised if it didn't include iptables support.  Maybe post what
distribution you're using, and your kernel version.
If you're using quite an old kernel (memory fails on how old, but at
least a couple of years) then it might support ipchains (the older
packet-filtering/firewalling code in Linux) not iptables.
