Trying to find a suitable vmmon module for your running kernel.

None of the pre-built vmmon modules for VMware Server is suitable for your 
running kernel.  Do you want this program to try to build the vmmon 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.

Your kernel was built with "gcc" version "4.1.3", while you are trying to use 
"/usr/bin/gcc" version "4.2.1". This configuration is not recommended and 
VMware Server may crash if you'll continue. Please try to use exactly same 
compiler as one used for building your kernel. Do you want to go with compiler 
"/usr/bin/gcc" version "4.2.1" anyway? [no] yes

What is the location of the directory of C header files that match your running
kernel? [/lib/modules/2.6.21-2-686/build/include]
