I'm running Ubuntu 12.10 and getting the following error when running specs:

```ruby
#<Errno::ENOENT: No such file or directory - /usr/releases/start_erl.data>
```

I've installed riak with `apt-get` and the location of `start_erl.data` file is `/usr/lib/riak/releases/start_erl.data`.

So, maybe this should be config or ENV variable?
