I have not come across that problem on standard Ubuntu, where ruby is
not installed by default. Google suggests that
gem install rdoc rdoc-data
might sort it, but I don't know.
By the way, if you want to get seriously into ruby then use rvm (or
possibly rbenv, but I have no experience of that myself) which will
manage versions of gems and ruby.
