$ rvm get latest
$ rvm reload
$ rvm pkg install readline
(skipping remove since I haven't installed 1.9.3 at all yet)
$ rvm install 1.9.3-preview1 --with-readline-dir=$rvm_path/usr
$ rvm use 1.9.3-preview1

$ ruby -v -e "p require 'readline'"

And it seems to be working in irb.  Can you tell us more about your host?
