Ruby and ri(1) ruby information

[Kevin O'Gorman]

I recently would up with a book on Ruby and got curious about it.
I discovered I have Ruby installed.  This was a fresh install of
xubuntu 13.04, so I assume it came with the distro.

Following the book (The Ruby Programming Language, O'Reilly) in the
first few pages it talks about things that come with.  Including the
ri command, and it gives examples.  None of them work -- they all say
"Nothing known about x"

Is there something I have done wrong?  Is there something I can do to
put it right?  Or is this time to file a bug?
