[lug] Kernel building failure on FC4

Hi all,
I have a Fedora Core 4 in my DELL 6000 laptop. It works nice, but I
have a problem with building new kernel from the kernel source FC4
itself have provided(in /usr/src/kernels/2.6.11-1.1369_FC4-i686/
directory).
All of documents about kernel building mention "make xconfig, make dep,
make clean and make bzImage" as sequence of commands for the process,
but after I change configurations (even with no changes) using "make
xconfig" problems appear....:

make dep says:
*** Warning: make dep is unnecessary now.

make clean says:
fs/hostfs/Makefile:11: arch/um/scripts/Makefile.rules: No such file or
directorymake[2]: *** No rule to make target
`arch/um/scripts/Makefile.rules'. Stop.
make[1]: *** [fs/hostfs] Error 2
make: *** [_clean_fs] Error 2

make bzImage says:
CHK include/linux/version.h
CHK include/asm-i386/asm_offsets.h
make[1]: *** No rule to make target `init/main.o', needed by
`init/built-in.o'. Stop.
make: *** [init] Error 2

Could you help me for solving the problem?
Cheers,
Habib
