make the internal speaker beep when a logfile has a new line

I had the following problem:
I wanted to be noticed if a logfile (an errorlog in this case) gets a new line.
This notification should be in form of a beep of the internal pc speaker. (No soundcard installed)

This beeping is done via a tiny perl script:

while ()    
  print $_;    
  print "\007";    
Just call the script the following way:
tail -n0 -f /var/log/mylogfile | path_to_script/beeper.pl

The script will put the new line to the console where it was started from.
If you don't want that, remove the print $_ line.
