retrieve_op_conf_from_mysql.pl

Hi -
I'm trying to get my trixbox working. When I try to apply a change in FreePBX, I get the error below. I try to run the script from the command line, but it seems like I need to set some environment variables? Any idea what the problem is? I can't reinstall as this is a production machine.
thanks
Todd
