 Update: It's because pacman is installing libevent, and its version of
 libevent wants openssl, and somehow it doesn't recognise that openssl is
 already installed.  Also, there's no way to tell pacman which version of
 openssl to install, because Arch is a steaming pile of crap made by
 masochists who like everything to be maximally broken all the time. I'm
 going to try building libevent from git instead, and get rid of this
 pacman garbage entirely.
