Yeh, it works!

$ head /home/wolf/.gem/ruby/1.8/bin/cucumber
#!/usr/bin/ruby1.8
$ /usr/bin/ruby1.8 -v
ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]

Now I try interactive ruby as described in 
http://www.ruby-lang.org/en/documentation/quickstart/

$ irb
The program 'irb' is currently not installed.  You can install it by 
typing:
sudo apt-get install irb

But my Ubuntu Software Center shows irb 1.8 “Installed”.  How can I get 
irb to run?

Is Ruby usually this difficult to setup on Ubuntu?  Are there some magic 
instructions I missed?

Thank you.
