Here's how I was able to compile modules from the Western Digital sources in Ubuntu Jaunty 9.04 (64-bit).
Keep in mind that you're going to need (at least) the following packages installed on our workstation: bison, flex, texinfo, libc6-dev-i386, build-essential .
1. tar -xzvf WD-MyBookWorld-v1.00.16-GPL.tar.gz
2. cd WD-MyBookWorld-v1.00.16-GPL/kernel/
3. tar -xzvf kernel-source.tar.gz
4. cd kernel-source
5. tar -xjvf buildroot-20080225.tar.bz2
6. cp -rf buildroot-patches/* buildroot/
7. cd buildroot
8. ./snapshot.patch . .
9. make defconfig
10. vim "target/makedevs/makedevs.mk" , Remove -Werror from
11. create the file "libusb-0.1.12-nocirc.patch" in "package/libusb/" , enter:
--- libusb-0.1.12/configure.in.orig 2006-03-04 03:53:04.000000000 +0100

12. cd to WD-MyBookWorld-v1.00.16-GPL/kernel/kernel-source/buildroot, run make
13. Eventaully it dies compiling gdb. To fix remove -Werror from "WD-MyBookWorld-v1.00.16-GPL/kernel/kernel-source/buildroot/toolchain_build_arm/gdbhost-6.6/bfd/Makefile"
14. run make again
15. Pretty soon thereafter, make will die. To fix remove -Werror from "WD-MyBookWorld-v1.00.16-GPL/kernel/kernel-source/buildroot/toolchain_build_arm/gdbhost-6.6/opcodes/Makefile"
16. run make again
17. cd ..
18. source ./setup-paths.sh
19. cd kernel-0.4.6
20. make oxnas_810_eabi_dse_defconfig
21. make menuconfig (Here's where you can adjust the existing modules and add your own)
22. make modules
