You should be installing RPMs as part of the build process.  You should
install Lustre's BuildRequires before building Lustre.

That is only going to work if you don't want to make lustre RPM
packages.  If you want to build RPM packages, you need to follow
standard RPM practices.  In other words, you need to have Lustre's
prerequite packages installed before you build Lustre's RPMs.

So you are going to need to those other kernel packages, and you need to
install them before building Lustre.
