Even  re-running   `make depend' may not catch all the necessary
dependencies.   Did you build a kernel without sysv IPC first?
If so, I'd use grep to find all references to SYSV in the kernel
source tree, and remove the .o files for all .c files that refer
to SYSV.

Or do
	`make clean; make cleandir; make'
but that  will be much slower.

Otherwise i'm not sure; I don't think I've ever used SYSV IPC myself...
