FAILED to load virtual box kernel module in Fedora 9 final

[p3tzata]

Hi, I am with kernel 2.6.25.3-18.fc9.x86_64

and install VirtualBox-1.6.0_30421_fedora9-1.x86_64.rpm

and
/etc/init.d/vboxdrv setup

 
Stopping VirtualBox kernel module        [  OK  ]
 Recompiling VirtualBox kernel module [FAILED]  
 (Look at /var/log/vbox-install.log to find out what went wrong)

cat /var/log/vbox-install.log

   which: no dkms in (/sbin:/usr/sbin:/bin:/usr/bin) Makefile:127: *** Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR=<directory> and run Make again.  Stop.

Thank you
