vmware-config can't find header files

[Joakim Arnling <arnling kth se>]

When I try to build vmhgfs module with vmware-config-tools.pl, the
suggested place for include is /usr/src/linux/include. It wasnt like
this prior to kernel 2.6.15-1.1907

I try to enter the right path
( /usr/src/kernels/2.6.15-1.1909_FC5-i686/include ) and gets this:

"The kernel defined by this directory of header files does not have the
same address space size as your running kernel." 

What do I do wrong?
