chruby + ruby-build / mksh

1. Install chruby and ruby-build with git. I keep their repo at ~/.chrb, their installation inside ~/local and my rubies at ~/.chrb/rubies.
2. Copy this in your ~/.mkshrc file

# chruby + ruby-build
chrb() {
    source ~/local/share/chruby/chruby.sh
    unset RUBIES
    RUBIES=$(ls -d ~/.chrb/rubies/* 2> /dev/null)
