Command not found error in shellscript cron job for Plesk 11

Hoping for a bit of advice or guidance on this one. I am not very familiar with most of this stuff but have managed to navigate and test and check to get to this point. Solving one error at at time!

Running Plesk 11.0.9 I am attempting to set up a simple Cron job running a shell script to detect mailboxes that are approaching full, so that I or the user can be notified and solve the issue.

Running the script as the root user under the assumption that this will check all mailboxes.

The script is from the Plesk forum (last post http://forum.parallels.com/showthread.php?106635-Qmail-e-mail-quota-notification-script-for-Plesk-9-3-10) where many users seem to have had success however on running the job I get this error

/usr/local/psa/bin/mboxfull.sh: line 26: bc: command not found

/usr/local/psa/bin/mboxfull.sh: line 32: bc: command not found

This seems like a very generic 'what is written won't work' error so my search hasn't given me much direction as to how to correct this issue.

Full script below with the 'offending' lines marked. Any help of direction would be very much appreciated!

Subject: Your mailbox is almost full
Dear mail user,

Your e-mail $MAILBOX@$DIR is about to reach its maximum quota. You are using $MBOXSPACE MB ($MBOXPERCENT%) out of the maximum quota $HARDQUOTA MB.

We would kindly suggest you to delete some older messages and purge them to free some space in the mailbox. If the quota limit is reached, you won't be able to receive any new messages and the sender will receive  'mail quota exceeded' notifications.

Another option is to configure your POP3 mail client (e.g. Microsoft Outlook, Mozilla Thunderbird or Apple Mail) to delete the messages on the server mailbox every time the mail account is read.

This is an automated message, do not reply. If you require any assistance, please open a support ticket at http://*******/support.php .

line 26: bc: command not found

means that "bc" utility is not installed on your server.

Try to install it by following commands:

# yum install bc

or for debian-like systems:

# apt-get install bc
