pkg_info -m shows the packages I installed explicitly, i.e., they are not just a dependency of something.
There's two packages that I indeed installed manually, namely libiconv and nspr, to build some third-party software (not ports). Now I no longer need them explicitly, but meanwhile they both became dependencies of other ports (mutt requires libiconv, firefox requires nspr). Is there a way to 'clear' the manually-installed flag on ports that once were manually installed, but now are just dependencies?
