VMware server cannot run on FC6

Dear All

I get the following problem when running the vmware-config.pl script. Any ideas?

Thanks in advance,

Paul

What is the location of the directory of C header files that match your running
kernel? [/usr/src/kernels/2.6.18-1.2798.fc6-i686/include]

There is probably a slight difference in the kernel configuration between the
set of C header files you specified and your running kernel.  You may want to
rebuild a kernel based on that directory, or specify another directory.
