OK - You were right Frank - however, making the sym links
build or source point to ...BUILD/kernel-2.6.29/linux-2.6.29.i586
and then building the vboxdrv exposed another problem:
missing header file include/linx/bounds.h

This file is prsent in /usr/src/kernels/2.6.29.6-213.fc11.i586

but not in the BUILD area which is set up by rpmbuild -bb kernel.spec

I don't know why this is so.

But, in order for me t move forward, I copied the missing header file
to the build area and the driver built and loaded without a  problem.

And Just as 
        w41te stated, I did a make clean  first before I ran
the vboxdrv setup.

Thank you for your help.

Cheers,

MK
