error while compiling kernel help ?!?

[Brent]

I was adding some options to my kernel on a Freebsd 4.10 machine and ran into
the following when i tried to run the last step of "make install"

simitar.bmyster.net(root)# make install
chflags noschg /kernel
chflags: /kernel: Operation not permitted
*** Error code 1 (ignored)
mv /kernel /kernel.old
mv: rename /kernel to /kernel.old: Operation not permitted
*** Error code 1
Stop in /usr/src/sys/compile/SIMITAR.


 
any help is greatly appreciated
