Ubuntu...?

Use this to find out what executable you're running:

$ which ruby
/usr/bin/ruby

Use this to find out what it actually is:

$ readlink -f /usr/bin/ruby
/usr/bin/ruby1.8

Use this to find out what package it belongs to:

$ dpkg -S /usr/bin/ruby1.8
ruby1.8: /usr/bin/ruby1.8

Use this to uninstall that:

$ apt-get purge ruby1.8

Note: If you have installed Ruby using Version/Environment managers like RVM or Rbenv then this method is not gonna work because Rubies will be installed as scripts not packages.
