http://www.rubyquiz.com/quiz26.html
I tried to do everything as indicated on this post but I get an error:

I have wikiserver.rb in a folder /library/webserver/documents/ruby
--------->
#!/private/opt/local/bin/ruby -rcgi

require "webrick"

server = WEBrick::HTTPServer.new( ort => 8080,
ocumentRoot => "cgi-bin" )

['INT', 'TERM'].each do |signal|
trap(signal) { server.shutdown }
end
server.start

and wiki.cgi in a folder /library/webserver/documents/ruby/cgi-bin
------------->
#!/private/opt/local/bin/ruby -rcgi

H, B = %w'HomePage w7.cgi?n=%s'

c = CGI.new 'html4'

n, d = c['n'] != '' ? c['n'] : H, c['d']

t = `cat #{n}`

d != '' && `echo #{t = CGI.escapeHTML(d)} > #{n}`

c.instance_eval {
out {
h1 { n } +
a(B % H) { H } +
pre { t.gsub(/([A-Z]\w+){2}/) { a(B % $&amp { $& } }
} +
form("get") {
textarea('d') { t } +
hidden('n', n) +
submit
}
}
}

I run ruby wikiserver.rb
then on the safari web browser
http://localhost:8080/wiki.cgi
---------->

How do I get this code to work? (using ruby 1.8.4)
