LinuxQuestions.org - Problems installing VirtualBox on Slackware 11.0

Hi. I've downloaded the "All distributions i386" VirtualBox version. On a website I've read this steps to follow:
1-Run the installer
2-Run /etc/rc.d/rc.vboxdrv setup to build the necessary kernel modules (it?s necessary to have the current kernel?s source on /usr/src/linux)
3-Add /etc/rc.d/rc.vboxdrv and /etc/rc.d/rc.vboxdrv to /etc/rc.d/rc.local to start on system boot
4-Add your user to the vboxusers group on /etc/group
I'm stuck at the secound step.

I do:

Code:

/etc/rc.d/rc.vboxdrv setup

and it gives me this output:

Code:

Root [~] --> /etc/rc.d/rc.vboxdrv setup

Stopping VirtualBox kernel module ...done.

Recompiling VirtualBox kernel module ...failed!

  (Look at /var/log/vbox-install.log to find out what went wrong)

so I go to see the log file:

Code:

make KBUILD_VERBOSE=1 -C /lib/modules/2.4.33.3/build SUBDIRS=/tmp/vbox.4 SRCROOT=/tmp/vbox.4 modules

make -C  /tmp/vbox.4 CFLAGS="-D__KERNEL__ -I/usr/src/linux-2.4.33.3/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=i486 -fno-unit-at-a-time -DMODULE" MAKING_MODULES=1 modules

make[2]: *** No rule to make target `modules'.  Stop.

make[1]: *** [_mod_/tmp/vbox.4] Error 2

make: *** [vboxdrv] Error 2

??

If I try to launch VirtualBox, it says:

Code:

WARNING: The vboxdrv kernel module is not loaded. Either there is no module

        available for the current kernel (2.4.33.3) or it failed to

        load. Please recompile the kernel module and install it by



          sudo /etc/init.d/vboxdrv setup



        You will not be able to start VMs until this problem is fixed.

then the program starts, but of course it doesn't work.
How can I complete the installation of this Virtual Machine? I have the kernel sources, as requested, at "/usr/src/linux/".

Useful info:

Code:

Root [~] --> cat /etc/slackware-version

Slackware 11.0.0

Code:

Root [~] --> uname -a
