No such file or directory

Hey there, just trying out githubwatcher but before I could get chance to try it I encountered the following error when I try to start it:

```
/Users/<username>/.rbenv/versions/1.9.3-p125/lib/ruby/gems/1.9.1/gems/foreverb-0.3.0/lib/forever/base.rb:17:in `chdir': No such file or directory - /Users/<username>/.githubwatcher (Errno::ENOENT)
```

Any thoughts on what could be causing this?
