Connection error when starting

[Jagermo]

Hi Elliott, sorry again.

I got another error when starting the bot:

./mumbletune -v -c conf.mumble.yaml            /home/jagermo/.bundle/ruby/1.9.1/mumble-ruby-8a557f55d2ba/lib/mumble-ruby/connection.rb:16:in `initialize': getaddrinfo: Name or service not known (SocketError)
        from /home/jagermo/.bundle/ruby/1.9.1/mumble-ruby-8a557f55d2ba/lib/mumble-ruby/connection.rb:16:in `new'
        from /home/jagermo/.bundle/ruby/1.9.1/mumble-ruby-8a557f55d2ba/lib/mumble-ruby/connection.rb:16:in `connect'
        from /home/jagermo/.bundle/ruby/1.9.1/mumble-ruby-8a557f55d2ba/lib/mumble-ruby/client.rb:29:in `connect'
        from /home/jagermo/mumbletune/lib/mumbletune/mumble_client.rb:29:in `connect'
        from /home/jagermo/mumbletune/lib/mumbletune.rb:59:in `block in <module:Mumbletune>'

The setup is running on a virtual Ubuntu 14.04 LTS, freshly set up for the bot (VMs are awesome). Do I need to install something else, like a mumble-client or something?
