logrotate is your friend.

 From the man pages:

  logrotate  is  designed to ease administration of systems that generate
        large numbers of log files.  It allows automatic rotation, 
        removal, and mailing of log files.  Each log file may be handled 
        weekly, monthly, or when it grows too large.

        Normally, logrotate is run as a daily cron job.

from what I remember you add your log file to the logrotate config and 
it rotates/emails/compresses/whatever on the schedule you specify.
