Getting Build-Id errors wth a systemtap build on ubuntu 9.10

[Kannan Ramaswamy]

Hi,
I was able to build the latest systemtap code on ubuntu 9.10 with elfutils 0.143 release code. But I am getting a "Build-Id mismatch between kernel and vmlinux error" when I run stap. I checked the instructions at http://sourceware.org/systemtap/wiki/SystemtapOnUbuntu. I am not sure what I am doing wrong. Has anyone come across this issue before?

Thanks,
