I am trying to install again virtual box after a new clean install of 11.2. After install and running: /etc/init.d/vboxdrv setup

I get error:
Stopping VirtualBox kernel module done
Recompiling VirtualBox kernel module failed
(Look at /var/log/vbox-install.log to find out what went wrong)

Here is the log file:

Makefile:162: Warning: using /usr/src/linux as the source directory of your Linux kernel. If this is not correct, specify KERN_DIR=<directory> and run Make again.
Makefile:170: *** Error: /usr/src/linux (version 2.6.31.12-0.1-desktop) does not match the current kernel (version 2.6.31.5-0.1-desktop). Stop.

I do not know what to do now.
