Ruby's readline takes input from stdin. Perhaps Perls takes from

The test exited immediately after printing the prompt, on my box.
What are your platform, ruby and readline versions?

I've experienced same problem with OP.

$ ldd /usr/lib/ruby/1.8/i686-linux/readline.so | grep readline
libreadline.so.4 => /lib/libreadline.so.4 (0xb7f00000)
$ ruby -v
ruby 1.8.2 (2004-12-25) [i686-linux]

Same on the 1.9 (March).
