perhaps
-----
#!/usr/local/bin/ruby
class Hello
     attr_reader :msg
     def initialize
         @msg = "Hello, World"
     end
end

print "content-type: text/plain\n\n"
h = Hello.new
puts h.msg
-----

since

   print "Press RETURN"
   $stdin.gets

doesn't seem to make sense in a server browser program;
and the browser wants to see some content header.

For stuff that should run from the commandline as well as on the server, 
I do

   if ENV['CMDLINE']
     # assign ARGV etc.
   else
     require 'cgi'
     cgi = CGI.new
     params = cgi.params
     # ...
   end
