Cannot load iconv in node.js inbox module

I've been doing some node.js development on Ubuntu 12.04 recently, but a bug in Ubuntu's openssl combined with the ridiculously bad battery life it affords my Zenbook, I've decided to boot Windows 7 again as my main OS. I checked my code in before shutting down Linux, and pushed everything to github. I cloned my github repo on Windows, ran 'npm install' with no errors, and then tried to run my app, but I get this error:

Line 1 of mime-functions.js is: var Iconv = require("iconv").Iconv;
