avrdude is part of the FreeBSD ports system. To install it, simply do the following:

# cd /usr/ports/devel/avrdude # make install

Building and installing on other systems should use the configure system, as such:

$ gunzip -c avrdude-<version>.tar.gz | tar xf - $ cd avrdude-<version> $ mkdir obj-avr $ cd obj-avr $ ../configure --prefix=$PREFIX $ make $ make install
