Yep, that is a runtime dependency rather that a buid-time dependency, but worth mentioning, because util-linux's build system doesn't build wall if the 'configure' script is passed a --disable-wall option, and, for example, Gentoo does not have that program unless explicitly requested by the administrator with the 'tty-helpers' USE flag.
