really?  i needed to

....
LoadModule fastcgi_module modules/mod_fastcgi.so
FastCgiIpcDir logs/fastcgi
....

....
ScriptAlias /fcgi-bin/ "/usr/local/httpd-2.0.47//fcgi-bin/"
....

....
<Directory "/usr/local/httpd-2.0.47//fcgi-bin">
    AllowOverride All 
    Options None
    Order allow,deny
    Allow from all
    SetHandler fastcgi-script
</Directory>
....

....
AddHandler fastcgi-script .fcgi
....

i suppose the only pertinent bits are the first and last ones...  did you
compile the fastcgi module in statically?  if not it would need loaded...

yeah - for me, using

  #!/usr/local/ruby-1.8.0/bin/ruby
  require 'cgi'
  require 'fcgi'

  FCGI.each_cgi do |cgi|
    content = ''
    env = []
    cgi.env_table.each do |k,v|
      env << [k,v]
    end
    env.sort!
    env.each do |k,v|
      content << %Q(#{k} => #{v}<br>\n)
    end
    cgi.out{content}
  end


i get around 20 requests per second from a very slow machine, uploading on a
cable connection,  to a machine behind some serious pack sniffing software in a
government firewall...  you've definitely got something wrong... are you
perhaps using the pure ruby fastcgi version?  i seem to recall there is one...
