Thanks Akemi,

I think I see the problem now.  A yum search produces only one listing 
for kernel-devel and yum info says:

Installed Packages
Name        : kernel-devel
Arch        : x86_64
Version     : 2.6.32
Release     : 279.9.1.el6


uname -a says
Linux <my fqdn> 2.6.32-220.17.1.el6.x86_64 #1 SMP Tue May 15 17:16:46 
CDT 2012 x86_64 x86_64 x86_64 GNU/Linux

I'm using the repo maintained by the collaboration I'm in and there 
seems to an issue.

For the record fixing that broken link did allow me to build the kernel 
module and run vbox.  I wonder if I introduced any instabilities.
