You don't need to compile everything. Just:
	cd /usr/src/sys; make includes
	cd /usr/src/lib/libkvm; make && make install
	cd /usr/src/sbin/ps; make && make install
	cd /usr/src/usr.bin/netstat; make && make install
	cd /usr/pkgsrc/sysutils/top; make clean && make && make reinstall

  That usually does it for me when I upgrade kernels. There are other
tools that use libkvm, but I never notice them.
