The error means that there are no Mail Transfere Agent (MTS) installed in your system. Therefor cron can not mail the standard- and error-out to your user.

Look at installing sendmail, postfix or similar MTA in your system, OR make sure to redirect standard-out and -error from the cron job to a file you can read.
