I had similar problems when I was beginning with Avrdude. Avrdude doesn't use /dev/lp0. Instead it uses /dev/parport0 (by default, so no need to specify it on the command line). /dev/parport0 may not exist on your machine. If you don't have it, you probably need to load the 'ppdev' kernel module. To get it running right now, you can load it by hand: as root, type "modprobe ppdev". The you can add it to /etc/modules so that it loads automatically every time you start your computer. On my machine, I also had to make myself part of the 'lp0' group, so that I can access /dev/parport0 as a regular user. Otherwise, you will only be able to use avrdude as root.
