This section of the post does not include the installation of GCC.
The was a how-to in the old wiki that incuded the install of GCC and is subsequent removal at the end of running vmware-config.pl .
The requrement for GCC is an optional maybe. Depending on your kernel at the time you may find the the included modules load and run perfectly (it will give you a message to this effect).
Also, be aware that a yum update that includes a new kernel may cause a failure of VMware-server. In this case, you will have to re-run vmware-config.pl and rebuild the modules.
Finally, VMware-server benefits from a lot of ram.
