There are reasons that packages sometimes are installed automatically as a dependency and there are reasons that such packages aren't needed anymore. The only reason that comes to mind, when a package management is "mistaken" is, if a package was installed automatically as a dependency, then the user installed software not by a package, e.g. by "make install" and this software needs such a package as a dependency, while it isn't needed by any package anymore. If such a package would be installed by the user and not automatically, as a "temporary" dependency, the package management would care about it.
IOW if you didn't install something without a correct build package, it should be safe to remove those packages. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected] Archive: http://lists.debian.org/1377120328.1535.46.camel@archlinux
