RubyGems should also check that the proper version is # installed. # # I think that RubyGems should optionally allow the user to inform it of a # manual installation when a gem is not found, prompting the user for the need # information (like version number installed). That particular gem would then # be entered into its gem-database as having been installed manually for # future use. # # Correspondingly, there should be an option to remove such a # manual-installation-entry from the RubyGems database. # I think this is a reasonable method of dealing with things. It feels like a temporary measure, which it ideally would be. Chad
