[Linux-cluster] building GFS-6.1 from SRPMS

[Jason]

anyone know if theres a howto for this?

Im trying to build from source on my 
Red Hat Enterprise Linux AS release 4 (Nahant Update 3)
box and get 

[root at tf1 ~]# rpmbuild -bs /usr/src/redhat/SPECS/GFS.spec 
error: Failed build dependencies:
        GFS-kernheaders >= 2.6.9 is needed by GFS-6.1.5-0.i386
[root at tf1 ~]# 

where does GFS-kernheaders come from? cant seem to find it.

regards,
Jason
