Openshift failing to load npm modules?

I'm trying to deploy an app that works on my local machine to openshift, and get this error repeatedly in the openshift logs.

DEBUG: Program node app.js exited with code 8

the package.json file I am using is

{
  "name": "restodb",
  "version": "0.1.0",
  "description": "Backend for AF resto database",
  "main": "app.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "async": "^0.9.0",
    [snip],
    "path": "^0.4.9",
    "request": "^2.40.0"
  },
  "devDependencies": {
    "grunt-shell-spawn": "^0.3.0"
  }
}

I logged into the app and can see that while there is a qs directory in the request node_modules it does not have a ./lib directory, which is very strange. Grateful for suggestions to try.
