Have you looked at my tool chain setup receipt (see below)? May be I need
another version of one of the ingredients!?? What components contains the chip
infos? Is this in avr-libc? I use v1.8.1. Which version do you have?
Thanks a lot,
Andreas

We sync avrdude-5.8 and arduino.sh from the 192.168.1.2
rsync -avz -e ssh arduino.sh avrdude-5.8 root@192.168.1.7:/usr/src/avr
and build as follows:
LIBUSB=/usr/sfw
export CPPFLAGS="-I${LIBUSB}/include"
export LDFLAGS="-L${LIBUSB}/lib"
make
make install
This installs
/usr/local/bin/avrdude
/usr/local/etc/avrdude.conf
We can now do
avrdude -c avrispmkII -P usb -p atmega8
