Broken `make test` -- Incorrect/changed paths

```bash
/bin/sh: 1: ./node_modules/.bin/mocha: not found
make: *** [test] Error 127
```

I don't know if the path is different between architectures, or has changed between versions, however the path to the mocha binary installed locally is `./node_modules/mocha/bin/mocha`, so the default "test suite" needs some work to do anything

(node v0.11.3-pre, npm 1.2.21)
