I get the following: # emerge -p --depclean * Depclean may break link level dependencies. Thus, it is * recommended to use a tool such as `revdep-rebuild` (from * app-portage/gentoolkit) in order to detect such breakage. * * Always study the list of packages to be cleaned for any obvious * mistakes. Packages that are part of the world set will always * be kept. They can be manually added to this set with * `emerge --noreplace <atom>`. Packages that are listed in * package.provided (see portage(5)) will be removed by * depclean, even if they are part of the world set. * * As a safety measure, depclean will not remove any packages * unless *all* required dependencies have been resolved. As a * consequence, it is often necessary to run `emerge --update * --newuse --deep @world` prior to depclean.

It seems like you need to add app-editors/vim to world if you want to keep it. Looking at the dependencies of app-editors/gvim-7.3.189, it pulls in ~app-editors/vim-core-7.3.189 as a dependency, but not app-editors/vim.
Ups, sorry a lot, I didn't remember vim-core stuff
