Subject: trouble with fcgi and cgi

I'm having a real difficult time trying to deploy rails demo app depot
on fedore core 4 clone centos-4.1. Please help.

I've installed ruby 1.8.3, gems 0.8.11, fcgi, mod_fastcgi, gem install
fcgi. set rails /log , /public, and /tmp/fcgi_ipc to 777. Tried
everything I know, just can't get it to work.

Problems:
------------
* on the same machine, app in webbrick runs fine.
* when using fastcgi, in httpd error log, i get:
  FastCGI: can't start server "/var/www/html/proj/public/dispatch.fcgi"
(pid 4644), execle() failed: No such file or directory

* when using cgi, in rails log/Server.log, i get:
  Exec format error: exec of '/var/www/html/proj/public/dispatch.cgi'
failed
   Premature end of script headers: dispatch.cgi


config files list below

dispatch.fcgi
----------------------
#!/usr/local/bin/ruby
require File.dirname(__FILE__) + "/../config/environment"
require 'fcgi_handler'
RailsFCGIHandler.process!


dispatch.cgi
----------------------
#!/usr/local/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"



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

Dispatcher.dispatch
