Assuming that your config.ini exists we can shorten the example to
> require "cgi"
> index = CGI.new("html3")
> print index.a("http://www.example.com"){ "Example" }

now if you execute this via the commandline you see this output
$ ruby test.cgi
(offline mode: enter name=value pairs on standard input)^D
<A HREF="http://www.example.com">Example</A>bschroed@oerfi:~/svn/projekte/ruby-things$

where one can see that the header lines are missing. Change the above to:

-----
#!/usr/bin/ruby

require "cgi"
index = CGI.new("html3")

index.out do
  index.a("http://www.example.com"){ "Example" }
end
------

and the output becomes
-------
Content-Type: text/html
Content-Length: 44

<A HREF="http://www.example.com">Example</A>
-------

This should work as a cgi script.

hope to help,

Brian
