osx - irb readline and rvm ruby 1.9.3 on OS X Lion -

i using os x lion , installed , linked readine using homebrew. furthermore compiled ruby 1.9.3 using rvm readline support.

rvm install 1.9.3 --with-readline-dir=$rvm_path/usr 

however, when start irb , try input accented chars (using option + e example), no character appears.

what doing wrong? or how can accented characters in irb (or pry) ?
