How are you running it daily? If running from cron, then cron should capture
your script's output and mail it to the cron user's uid.

Otherwise you could do something like
  IO.popen("sendmail you@yourdomain.com","w") do |io|
    io << EOM
From: system@yourhost
To: you@yourdomain.com

Something nasty has happened!
EOM
  end

YMMV (you didn't say if this was Windows or Linux/Unix or something else)
