I will only be implementing the changes in the planned layout only this cleanup. That means I wont be moving system-wide installation to /var/.. yet Don't worry, I wont forget about users that use gem to install to system wide locations. As already mentioned, I will make the default gem install to $HOME/.gem/ruby and if you so choose, you can edit your gemrc to install to the system wide location (/usr/lib.. for now). > Can you clarify if you're planning to make it impossible to use gem to install > system gems?

System wide installation of gems by default will be disabled. If you want system wide gems, either run gem with the --no-user-install flag like "sudo gem install --no-user-install foo" You can also install to the system wide location by removing --user-install from /etc/gemrc
