Cabal and --no-require-sandbox

Question

In my ~/.cabal/config file, I have

require-sandbox: True

According to the Cabal User Guide, I should be able to override this like so:

amy@wombat$ cabal install xmonad xmonad-contrib --no-require-sandbox
cabal: unrecognized 'install' option `--no-require-sandbox'

What am I doing wrong? I'm using cabal-install version 1.21.0.0.
