Node.js - Module Version Mismatch on Linode Server

I am trying to deploy a node app on Linode (Ubuntu 12.04) while following this guide from Node Knockout: http://blog.nodeknockout.com/post/9300619913/countdown-to-ko-14-deploying-your-node-js-app-to

I have no problems running the server as root, but when trying to start the server as the "deploy" user using sudo start node, I get this error:

   /home/deploy/app/source/node_modules/bcrypt/node_modules/bindings/bindings.js:79
            throw e
                  ^
    Error: Module version mismatch. Expected 11, got 1.

I have tried recompiling bcrypt using make clean then make since I thought my module version was incompatible with my version of node (v0.8.18), but that does not seem to be the case since I can start the server as root with no problem. I feel as though the problem lies in how I set up the deploy user, but I am not sure how to proceed.
