Thanks for the quick reply Horms. Your response didn't entirely solve
the problem, but it did point me in the right direction. Apparently the
key is the net/netsyms.c file. IPVS applies a patch to this file which
confuses ktcpvs. In order to compile ktcpvs successfully, one must
ensure that they have a clean kernel *without* any patches. So basically
a IPVS+ktcpvs build would go like this:
1. extract and build fresh kernel (include IPV6 & KHTTPD)
2. reboot with new kernel
3. build / install ktcpvs
4. patch kernel with hidden ARP patch
5. ipvs - make patchkernel
6. ipvs - make installsource
7. kernel - make menuconfig / make dep
8. ipvs - make / make install
9. kernel - make dep / make bzImage / make modules / make
modules_install install
10. reboot
At least that's what it took to get it working on my machine.

>From examining net/netsyms.c in the kernel source you would have
noticed that the export of each of these symbols is surrounded by
#if defined (CONFIG_IPV6_MODULE) || defined (CONFIG_KHTTPD) || defined
(CONFIG_KHTTPD_MODULE)
I would suggest reconfiguring your kernel with one of these options
enabled or removing the #if ... #endif. Whichever takes your fancy.
In either case you will need to rebuild your kernel.
