Error When Running make flash On Arch Linux

Hello,

When running make flash on my Arch machine, I get the following error and warning.

To update your keyboard’s firmware, hold down the ‘Prog’ key on your keyboard,
and then press ‘Enter’.

When the ‘Prog’ key glows red, you can release it.

I figured out that I had to set my ARDUINO_PATH to /share/Arduino, and in place of arduino use arduino-git. I’m not sure what the avrdude errors are about; has anyone had a similar problem and know of a solution?
