v0.6 doesn't install properly on windows

I get the following output from NPM when running `NPM install -g nodeunit`:

```
npm WARN nodeunit@0.4.0 package.json: bugs['web'] should probably be bugs['url']

npm ERR! cb() never called!
npm ERR!
npm not ok
```

And running `nodeunit` in the command line results in:

```
C:\Users\Wilson\Documents\Sites\meshmesh-node\app>nodeunit
'nodeunit' is not recognized as an internal or external command,
operable program or batch file.
```

I have fallen back to version 0.4 which does install properly but lacks `setUp` and `tearDown` features :(
