Yes.  It lies.  It's VB's inimitable way of saying "you have the wrong
module version for this kernel".  It should be sufficient to rebuild
the virtualbox-ose-kmod port.  Don't install the package, because it
doesn't know what kernel you have.

I also rebuilt virtualbox-ose, but that's quite a pain and I don't
think it's necessary.  See

for more details.

When you're done, 'kldload vboxnetadp' should be enough.  That will
load the other modules.
