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](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
