Stopping VMware Tools services in the virtual machine:
   Guest operating system daemon:                                      done
Trying to find a suitable vmhgfs module for your running kernel.

None of the pre-built vmhgfs modules for VMware Tools is suitable for your 
running kernel.  Do you want this program to try to build the vmhgfs module for
your system (you need to have a C compiler installed on your system)?

The directory of kernel headers (version @@VMWARE@@ UTS_RELEASE) does not match
your running kernel (version 2.6.18.2-34-default).  Even if the module were to 
compile successfully, it would not load into the running kernel.

What is the location of the directory of C header files that match your running
kernel? [/usr/src/linux/include]
