Gentoo handles this by categorizing packages into a format like app-editors/vim. This way packages in different categories can share the same name:
dev-lang/crystal (The Crystal Programming Language)
games-mud/crystal (The crystal MUD client)
x11-themes/crystal (Crystal decoration theme for KDE4.x)
When installing packages, if a package having a unique name across all categories, a simple "emerge vim" will install it. Otherwise, the category can be specified with "emerge dev-lang/crystal".
