You are attempting to call the unary operator + on cgi.b, which returns a
string. In Ruby's internals the unary + is actually the +@ method. This
code works:

require "cgi"

cgi=CGI.new("html4")

cgi.out {

 CGI.pretty(
  cgi.html{
   cgi.head{
    cgi.title{ "testpage" }
   } +
   cgi.body{
    cgi.form{
     cgi.table( {'border' => '1'} ){
      cgi.tr {
       cgi.td{ "hello"} +
       cgi.td {"world"}
      } # end tr
     } # end table
    } +# end form <--NOTE WHERE THE PLUS IS
   cgi.b {"hello world in bold"}
   } # end head
  } # end html
 ) # end CGI#pretty

} # end cgi.out
