Subject: CGI.pretty Error

Hi,
I am trying to run a CGI script from "Programming Ruby" book and getting an
error.
The script runs on AIX version 4.
I built the Ruby on AIX with "IBM C and C++ Compilers. version 3.6.6".
Has anyone dealt with this error ?
Thanks.
Here is the error:
/home/fpse/ruby/lib/cgi.rb:966:in `gsub': Stack overflow in regexp matcher:
/<(?:.|\n)*?>(?!\n)/n (RegexpError)   from /home/fpse/ruby/lib/cgi.rb:966:in
`pretty'   from rubycgi.rb:6   from rubycgi.rb:4:in `out'   from
rubycgi.rb:4

Here is the script:
require "cgi"
cgi = CGI.new("html3")  # add HTML generation methods
cgi.out {
  CGI.pretty (
    cgi.html {
      cgi.head { cgi.title{"TITLE"} } +
      cgi.body {
        cgi.form {
          cgi.textarea("get_text") +
          cgi.br +
          cgi.submit
        } +
        cgi.h1 { "This is big!" } +
        cgi.center { "Jazz Greats of the 20" +
          cgi.small {"th"} + " century" + cgi.hr
        } + cgi.p + cgi.table ('BORDER' => '5') {
          cgi.tr { cgi.td {"Artist"} + cgi.td {"Album"} } +
          cgi.tr { cgi.td {"Davis, Miles"} +
          cgi.td {"Kind of Blue"} }
        }
      }
    }
  ) # CGI.pretty is a method call, not a block
}
