Look at AppNote AVR109.  You can find my GCC port of that code at

http://www.sax.de/~joerg/AVR109-gcc.tar.gz

AVRDUDE can talk to AVR109-style bootloaders (which is basically the
AVR Butterfly bootloader, generalized to handle about any AVR that can
self-program).

Note that avr-libc 1.4.3 had a bug in <avr/boot.h>:

Not sure whether this will affect you.
