make depend is failing

[Chad Lauterbach]

I'm receiving the following error when trying to do a make depend on my 
new kernel.  I'm running FreeBSD 4.8-RELEASE and I installed the kernel 
source from the same cd I installed from.

../../dev/fxp/if_fxp.c:81: miibus_if.h: No such file or directory
../../dev/fxp/if_aue.c:96: miibus_if.h: No such file or directory
mkdep: compile failed
*** Error code 1

Thanks,

Chad
