RVM + 1.9.3pre == broken readline

ruby-talk
1

I have not been able to get readline working with the 1.9.3 preview using
RVM. The results of my most latest attempt follow:

    Readline was unable to be required, if you need completion or history
    install readline then reinstall the ruby.
    You may follow 'rvm notes' for dependencies and/or read the docs page
    https://rvm.beginrescueend.com/packages/readline/ . Be sure you 'rvm
    remove X ; rvm install X' to re-compile your ruby with readline
    support after obtaining the readline libraries.

I did, by the way, try following the instructions at the referenced URI
(replacing "1.9.2" with "ruby-1.9.3-preview1"). No dice. Any
suggestions on how to resolve this problem would be appreciated.

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

Just for completeness' sake, (and because I hope it works this time, for
some reason -- or maybe because I'm a glutton for punishment) I'll do it
all again:

    $ rvm get latest

    Original installed RVM version:

    rvm 1.8.3 by Wayne E. Seguin (wayneeseguin@gmail.com)
    [https://rvm.beginrescueend.com/\]

    You already have the latest version!
    $ rvm reload
    RVM reloaded!
    $ rvm pkg remove readline
    (elided output)
    $ rvm pkg install readline
    (elided output)
    $ rvm remove ruby-1.9.3-preview1
    (elided output)
    $ rvm install 1.9.3-preview1 --with-readline-dir=$rvm_path/usr
    (elided output)
    $ rvm use 1.9.3-preview1
    Using /home/user/.rvm/gems/ruby-1.9.3-preview1
    $ ruby -v -e "p require 'readline'"
    ruby 1.9.3dev (2011-07-31 revision 32789) [x86_64-linux]

Elided output is here (plus the require 'readline' output):

Thanks; trying again on another host:

I still don't know what's going on then, sorry.

Thanks. I had no idea that existed. "gem install rb-readline" solved
the problem.

I'm still a bit mystified by the fact the standard readline wouldn't
work, though.
