How do I stop this?

User configuration file is "/Users/billbee/.avrduderc"
User configuration file does not exist or is not a regular file, skipping

User configuration file is "/Users/billbee/.avrduderc"

the config file is averdude.conf
and it is located in the installed arduino\hardware\tools\avr\bin folder
you need to check the command that you have entered.

It's not an error. It just states that you don't have a user specific config file.

avrdude will use a default one instead.

This is correct behavior when there is no user-specific avrdude config file. Since an installation of the Arduino IDE does not use a user-specific avrdude config file, but rather specifies the path to one in a different location, this message is expected. If this message did not appear, I would be concerned.

thanks. i deleted it and nobody died!
