During the installation process of VMware Workstation 9 some modules need to be compiled but unfortunately Workstation 9.0.1 doesn’t seems to be able to find by itself the correct kernel headers directory.
If kernel headers aren’t already installed, open the terminal and type as root: yum install kernel-*.
Wait for the process to be completed and then: sudo cp /usr/src/kernels/kernel_version.fc18.x86_64/include/generated/uapi/linux/version.h /lib/modules/kernel_version.fc18.x86_64/build/include/linux/.
This should do the trick.
