It was that the build script was very strict on what the kernel was named to
determine what patches to apply, this was an issue with the script from
Lustre. It's been almost a year since I've built Lustre, so this may have
changed.

The attachment did not make it, I'm downloading the current Lenny Lustre
packages to view the file.

Yes, all the vanilla patches that Lustre have are in the Debian package, the
problem is that Lustre is usually behind Lenny so grabbing the newest kernel
from kernel.org fails no matter what distro. What I've found about Debian is
that the package team has worked hard to patch Lustre for the current kernel
supported by Debian, this is usually a version or two ahead of Lustre. That
is why I said not to use a vanilla kernel, your chance of an error free
build is greater.
