kill USE flag will typically creates a conflict between the sys-process/procps and sys-apps/util-linux packages. Both packages include the kill command, and both packages are capable of conditionally building the kill utility by setting the
kill USE flag (in fact, sys-apps/coreutils also includes support for a kill command).
The mesg, wall, and write utilities are installed using the
tty-helpers USE flag. This can be viewed by scrolling down in USE flags section above.
For security reasons, these utilities are disabled by default.
