I see you are on windows - as the error message says, the fork is not
implemented there.
These are you options (maybe more):
1. use fork from the win32-process gem. see
http://rubyforge.org/docman/view.php/85/707/README.html for caveats
2. remove the fork call from the daemons lib code
3. reuse code from mongrel_service and/or win32-service gems
