Is it working under ruby 2.0.0?

When I try to start the debugger (`:Rdebugger` in Gvim) I get message:

```
Debugger started
```

But in ruby_debugger_output there is a message:

```
Uncaught exception: cannot load such file -- /path/to/my/app/script/rails
```

And debugger is not working at all. I use ruby 2.0.0 is it a problem, maybe there is some easy solution?
