I figured this out after some serious head scratching.
Here is a short description of getting ruby_fcgi and mod_fastcgi for 
Apache to work.

In httpd.conf you must have something like this


<IfModule mod_fastcgi.c>

     # URIs that begin with /fcgi-bin/, are found in /var/www/fcgi-bin/
     Alias /fcgi-bin/ /var/www/fcgi-bin/
     FastCgiIpcDir /var/fcgi/
     #FastCgiConfig -autoUpdate

     # Anything in here is handled as a "dynamic" server if not defined 
as"static" or "external"
     <Directory /var/www/fcgi-bin/>
         Order allow,deny
         Allow from all
         SetHandler fastcgi-script
         Options +ExecCGI
     </Directory>

     AddHandler fastcgi-script .fcgi .fpl

#-------------------------------------------------------------------------
     # Start a "static" server at httpd initialization

     FastCgiServer /var/www/ebw/echo

	Alias /ebw/ /var/www/ebw/
</IfModule>
------------End of httpd.conf--------------------------------

----------sample scripts---------------------
A Dynamic fcgi script
	It starts and continues to run when browser
         points to http://somedomain/fci-bin/ebw/echo.fcgi

cat /var/www/fcgi-bin/ebw/echo.fcgi
#!/usr/local/bin/ruby
   require 'rubygems'
   require 'fcgi'
   require 'cgi'
   FCGI.each_cgi {|cgi|
     puts cgi.header
     puts "Connecting from #{cgi.remote_addr}<br>"
     puts "Time is now #{Time.now.strftime("%Y-%m-%d  %H:%M:%S")}"
   }


A Static fcgi script
	It starts when the apache webserver starts
	It continues to run
	browser points to http://somedomain/ebw/echo    #look at Alias in 
httpd.conf above.
cat /var/www/ebw/echo
#!/usr/local/bin/ruby
   require 'rubygems'
   require 'fcgi'
   require 'cgi'
   FCGI.each_cgi {|cgi|
     puts cgi.header
     puts "Connecting from #{cgi.remote_addr}<br>"
     puts "Time is now #{Time.now.strftime("%Y-%m-%d  %H:%M:%S")}"
   }
