custombuild reports error. tput: No value for $TERM and no -T specified

Hi.
I get a error mailed to my root account about custombuild.
Can someone tell me what's wrong here? I copy&paste the mail.

Subject: Cron <root@server> test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )

/etc/cron.daily/custombuild:
tput: No value for $TERM and no -T specified
tput: No value for $TERM and no -T specified


How can I correct this?
