It's currently not possible for unprivileged users to refresh keys, which can be a security problem because it means that they don't have a way to ensure that the keys they are using have not been revoked for some reason. As a solution, I'd suggest to give the 'verify' subcommand a --refresh option, which refreshes the keys in a temporary directory if the user does not have write privileges to files installed by gentoo-keys.
app-crypt/gkeys is last rited now.
Removing.
