Well I always check the dependencies of the file:
CODE
pacman -Qi libfetch


If no dependencies are still needed, then yes, remove it:
CODE
pacman -Rs libfetch

Personally I don't bother removing packages listed as not needed, as the space gained is usually inconsequential. Debian has the deborphan package to find these, but it's highly recommended to research each removal as it can be hazardous to remove them willy-nilly.

In Gentoo, the following command removes unused packages.
CODE
emerge --depclean

I've learned to put as few things in the world file as possible and let portage choose what I need and don't need.  Portage pulls the dependencies in and when they're not needed anymore, depclean automatically removes them.

The world file contains a list of packages that you have specifically installed, but not the dependencies.  For instance, I emerge (install) gnome and the xorg server is pulled in as a dependency.  Gnome would then be in the world file, but the xorg server would not.

Packages in the world file are not removed by depclean unless specified with the depclean command.  Depclean won't remove anything that is a dependency.

Slackware is too cool to care about silly stuff like this. So what if there's a bit of dust and detritus under the bed. Who's gonna' bend down there to look? Those other distros are just too obsessive-compulsive. It's a hand-washing thing, I think. wink.gif

I think I had Slackware once, but it wasn't in the world file.  Gentoo must have uninstalled it.
