I've corrected the packages and uploaded it. (avr-binutils , avr-gcc and avr-libc)
they will be available on our repository soon (maybe 1-2 days).
Test them and tell me if they work fine.
I've tested them on the machine that I use for the packaging and I didn't have any problem.
I didn't test avrdude yet,so if you can try it, I will be very pleased.
Thanks for the segnalation.
