Redmine

Under Webrick in http://localhost:300 Redmine runs well.
Now trying to start it under apache mod_cgi like here: http://www.redmine.org/projects/redmine/wiki/HowTo_configure_Apache_to_run_Redmine
I get 500 Internal server Error.
And I don`t understand how to fix this err.

May be useful data:

Apache vhost:

dispatch.cgi:

#!"e:/server/Ruby187/bin/ruby" 

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

# If you're using RubyGems and mod_ruby, this require should be changed to an absolute path one, like:
# "/usr/local/lib/ruby/gems/1.8/gems/rails-0.8.0/lib/dispatcher" -- otherwise performance is severely impaired
#require "dispatcher" 
require "e:\server\Ruby187\lib\ruby\gems\1.8\gems\rails-2.3.11\lib\dispatcher.rb" 

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

I trying to start it with http://localhost/dispatcher.cgi in my browser
