I second Thomas' suggestion of `./configure --with-spec=redhat`.  
The kver packages built without that configure flag do not supply the
ksym deps.  In fact, if you build a kmod-zfs with the same ZFS version
(e.g.  2.1.2) as the other ZFS RPMs in the Whamcloud repository, you
should not even need to rebuild the Lustre kmods (or install the ZFS
devel and debug packages), and just be able to use your kmod-zfs with
the pre-built packages in the Whamcloud repository.
