cron job mergelog failure

[Tony Baldwin <tony@tonybaldwin.org>]

I have the following in my root crontab on my webserver:

0 1 * * * mergelog /var/log/apache2/access.log
/var/log/apache2/other_vhosts_access.log /var/log/apache2/my.log >
MY.log
  4 2 1 * * * mv /var/log/apache2/MY.log /var/log/apache2/my.log
    5 5 1 * * * webalizer

Every day I get an e-mail telling me this failed.

Now, I can go in and to this manually, 
mergelog my.log access.log other_vhosts_access.log > MY.log
# to merge the existing merged log with the new logs
the 
mv MY.log my.log
to move the newly merged log to my.log (which webalizer is configured to
read)
run webalizer
profit.

Why can't cron do it without my intervention?
