Runing Server, part of installation process

Hello,

I'm running my firs RoR project and I'm trying to install all to work on my PC, running on XP. I managed to create my firs project but when I need to run server I get error:

so I type: rails server

Otto@deus-eus ~/rails_projects/first_app
$ rails server
