Missing Kernel Build Directory?

[Chris Spencer]

I was trying to compile the x10dev device drivers when I got the error:

make: *** /lib/modules/2.6.14-1.1637_FC4smp/build: No such file or 
directory.  Stop.
make: Entering an unknown directorymake: Leaving an unknown 
directorymake[1]: *** [default] Error 2

I checked, and sure enough, /lib/modules/2.6.14-*/build and 
/lib/modules/2.6.14-*/source are all broken links.

Is there anyway to fix this? What should they be pointing to?
