Cannot find phantomjs binary in project node_modules

[ckundo]

When I install the cli via npm and run quail eval twitter.com, I expect to see some messages, but instead get an error:

Error: Cannot find module '/path/to/project/node_modules/phantomjs/bin/phantomjs' at Function.Module._resolveFilename (module.js:338:15)

It looks to me like the cli is looking for phantomjs to be a local dependency, but I'd expect it to use the global phantomjs binary (located in /usr/local/bin/phantomjs on OS X).
