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)? [yes]

Using compiler "/usr/bin/gcc". Use environment variable CC to override.

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

The directory of kernel headers (version @@VMWARE@@ UTS_RELEASE) does not match
your running kernel (version 2.6.18-4-amd64).  Even if the module were to
compile successfully, it would not load into the running kernel.
