error: use of undeclared identifier 'openpty'

[Noah]

I get this error when installing on Mac. Apparently there is a way to fix this same problem in pty.js by editing a src/unix/pty.cc file, but I don't see a similar file in tty.js to edit.

users-Air:learyounode user$ npm install -g tty.js

> pty.js@0.2.3 install /usr/local/lib/node_modules/tty.js/node_modules/pty.js
> node-gyp rebuild
