>Description:
Installing zsh using pkgin will pull in 210 additional packages.
Installing the same using pkg_add pulls in zsh and nothing else.
>How-To-Repeat:
Install NetBSD, upgrade to latest HEAD, then install pkgin.
Install zsh using "pkgin in zsh" -- will pull in 210 pkgs.
Try the same with pkg_add: only zsh will be pulled in, if you installed bash before.
