How to turn OFF auto update?

hi folks,
I was enjoying the calculate until very recent time when strange things starts to happening.

First of all, I am unable to disable auto updating.

/etc/calculate/calculate.env 
cl_autoupdate_set = off

But emerge world keeps executing anyways.

Could anybody point me to the solution?

soda

remove string containg

/usr/bin/nice -n19 /usr/sbin/cl-update -p --wait-another-update off

from <</etc/crontab>>

Variable will be, but not now.

Iurii, I was trying to edit crontab with crontab -e ,and I see empty file.
After the vim /etc/crontab I was able to locate the source of cl-update execution.
Thanks for the help!
