Tengo este error en metasploit sobre Debian Wheezy alguna ayuda?

Gem::InstallError: metasploit-concern requires Ruby version >= 2.1.
An error occurred while installing metasploit-concern (0.4.0), and Bundler
cannot continue.
Make sure that `gem install metasploit-concern -v '0.4.0'` succeeds before
bundling.
