package oss4-dkms 4.2-build2002-2 failed to install/upgrade: oss4 kernel module failed to build

[Rene E. Kohlhauser]

I tried to open virtualbox

This came up:
A virtuális gép munkamenetének megnyitása sikertelen: XP_UBUNTU.
The virtual machine 'XP_UBUNTU' has terminated unexpectedly during startup with exit code 1.

Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing

'/etc/init.d/vboxdrv setup'

as root. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.

I tried: /etc/init.d/vboxdrv setup

this came up:
kor@PowerLab:~$ /etc/init.d/vboxdrv setup
 * Stopping VirtualBox kernel modules [ OK ]
