If you can't find a dports option, then, you probably need to update your dragonfly system to current to find the option to install dports. If its a totally new install, you might be able to install from a nightly snapshot image and use that, otherwise you have a lengthy process to update and switch from a 3.2 release image with pkgsrc to 3.3-development (master) with dports.
cd /usr make src-create if that fails, rm -rf /usr/src and try make src-create again if it reports the src branch is release then you'll need to cd /usr/src && git checkout master make buildworld make buildkernel make installkernel make installworld make upgrade reboot Then the make dports options should be there...
