The node specific issues for this don't work.

For example, the following generates a bunch of errors if you run on node 0.10.26:

```javascript
var meSpeak = require("mespeak")
meSpeak.loadVoice(require("mespeak/voices/en/en-us.json"))
process.stdout.write(meSpeak.speak("hello world", {rawdata: "buffer"}))
```

Fix this and I'll merge it back in.
