Rebuilding Kernel Sources for 2.6.11 rawhide

[Dwaine Garden <DwaineGarden@xxxxxxxxxx>]

I'm trying to rebuild the kernel sources.  Getting the following error 
message.

[root@www SPECS]# rpmbuild -bp kernel-2.6.spec
error: Architecture is not included: i386
[root@www SPECS]#

Is there any other way which I can install the kernel sources with yum 
from rawhide?  
I'm using kernel-2.6.11-1.755, and need to compile some stuff.

Thanks
Dwaine.
