Subject: rio and ruby 1.9

This week I am trying to move my development from ruby 1.8 to ruby 1.9
(ruby 1.9.1p243 (2009-07-16 revision 24175) [i686-linux]). I have pass
through most of the hurdles, but one I can not fix is 'rio' library. I
am using it extensively in my code. I am having following issue when I
do "require 'rio'" in irb. Are there anybody who have fix this or can
point me what I need to do to fix this. Thanks.
