fasd `j` command not found

[squarefrog]

I'm trying out presto as a replacement for oh-my-zsh. I'm trying to use fasd but I'm unable to use the jump command:

j dir
zsh: command not found: j

My .zpreztorc module looks like the following:

zstyle ':prezto:load' pmodule \
  'environment' \
  'terminal' \
  'editor' \
  'history' \
  'directory' \
  'spectrum' \
  'utility' \
  'completion' \
  'git' \
  'osx' \
  'rsync' \
  'fasd' \
  'homebrew' \
  'tmux' \
  'history-substring-search' \
  'prompt'

Calling the alias reference fasd_cd -i dir also produces an error:

zsh: command not found: fasd_cd

Do I need to specifically reference the fasd alias somewhere in that file?

I didn't realise I had to install fasd separately. If anyone else has this issue, simply:

brew install fasd
