There’s a new tool being put together for pkgsrc installation and management, called pkg_dry. There’s an initial version for download with instructions from its creator, Emile “iMil” Heitor. It looks to duplicate the functionality of apt-get or yum, by handling binary-only remote package management.
Someone please test this on DragonFly, though not on a production machine… If it does end up matching apt-get (the only thing I like in Debian) in terms of functionality, that will be fantastic! I have wanted something like this for a while.
