Redmine ruby run

i installed redmine with this manual: http://www.redmine.org/wiki/Redmine/HowTo_Install_Redmine_in_Ubuntu but when i try to run redmine i got:

 #!/usr/bin/ruby

require File.dirname(__FILE__) + "/../config/environment" unless defined?(RAILS_ROOT)

require "dispatcher" 

ADDITIONAL_LOAD_PATHS.reverse.each { |dir| $:.unshift(dir) if File.directory?(dir) } if defined?(Apache::RubyRun)
Dispatcher.dispatch

as text. what could it be? ruby is no开发者_Go百科t running? done.forgot to configure nginx :)

suggest using mod_rails or mongrel

If you're using Apache, check out these instructions. They're for Debian, but I believe it works pretty much similarly for Ubuntu.
