Possible missing dependency (chokidar)

I encountered the following while investigating diagrams. I'm unsure if this is an environmental issue on my side. Certainly chokidar is not listed in whats currently at: https://github.com/francoislaberge/diagrams/blob/master/package.json

# sudo npm install -g diagrams

/usr/local/bin/diagrams -> /usr/local/lib/node_modules/diagrams/bin/diagrams.js /usr/local/lib └── diagrams@0.8.1

# diagrams watch

module.js:472 throw err; ^ Error: Cannot find module 'chokidar'

# sudo npm install -g chokidar
