Actually this has nothing to do with avrdude. avrdude is used to program
AVR devices. He got issues with avr-gcc, so basically there is nothing
to upload. Furthermore I think the Arduino IDE does take care of
uploading and issues like this.

This can (and to my opinion should) be changed, so you don't need to be
root. See [1] for some examples for various programmers.

First of all you should try to use the upstream package, which can be
downloaded here [2]. It already contains the necessary tool chain
(including avr-gcc and/or avr-g++), so it probably should work just
fine. If it does function, you can then look into the reason why your
setup doesn't work.
