[solved] building the kernel headers for custom kernels

Question

well, ive been building several different kernels for my laptop, so that i can test stuff. but ive got a problem with the kernel headers.
ive mirrored the arch kernel's PKGBUILD and modified some naming to get a custom kernel. but when i try to build a custmo module, it complains the headers are broken. (example, vbox_build_module).
im pasting the pkgbuild here for future reference...if someone sees something thats plain wrong, please say so.
thanks

for anything that might be missing. The error message when compiling would give you more of a clue. Off-hand, you may need to add 'generated', as I recall I needed that when the kernel moved to 2.6.33.
Problem with vbox_build_module after Kernel update.
Would you care to elaborate for us less versed in "Linux Geek" skills?
Thanks.......
