vboxdrv installation failure on fedora 7

[mm132]

this is the first time i try to install virtualbox on fedora
now based on what i read on various places this is what i did:
this is a fresh install of fedora 7
deactivated SElinux
installed all the patches
installed kernel-devel and kernel-headers (for version 2.6.21-1.3228.fc7)
installed virtualbox using the supplied rpm on the website
then i run
sh /etc/init.d/vboxdrv setup
the result is the standard
Stopping VirtualBox kernel module [ OK ]
Recompiling VirtualBox kernel module [FAILED]

so i look at the the log and i get this:

cp: missing destination file operand after `/tmp/vbox.3/Module.symvers'
Try `cp --help' for more information.

apparently, gcc isn't installed on your system.
