How to get Readline support in IRB using RVM on Ubuntu 11.10
I have tried everything I can think of to get this to work, to no avail so here I am requesting suggestions on how to debug.
Firstly, runnning Ubuntu 11.10
Installed rvm:
$ bash < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
Installed readline using apt-get:
$ sudo apt-get install libreadline-dev
Check for readline install:
$ dpkg --get-selections | grep readline
lib64readline-gplv2-dev install
lib64readline5 install
libreadline-dev install
libreadline5 install
libreadline6 install
libreadline6-dev install
readline-common install
Install ruby, with readline support?
$ rvm install 1.9.2 --with-readline-dir=/usr
Here is rvm version:
$ rvm --version
rvm 1.9.2 by Wayne E. Seguin ([email protected]) [https://rvm.beginrescueend.com/]
Lets try the ruby shell:
$ irb
1.9.2 :001 > puts "add history"
add history
=> nil
1.9.2 :002 > ^[[A^[[A^[[A^[[A^[[A <------ PRESS UP ARROW DOES THIS
No, ok so if its not going to work with ubuntu's readline version??? lets try with rvm's own version of readline:
$ rvm pkg install readline

Ok, there's an error there, lets take a look:

And as expected irb isn't working with readline:

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.

Answer
Ubuntu 12.04 here: the answers here helped, but were also misleading.
If you're using Ubuntu 12.04, DO NOT pkg install readline, with or without --skip-autoreconf. After you've done that, either readline or zlib will be broken no matter what combination of switches you give to rvm install 1.9.3.
To get it to work, do the apt-get install that rvm requirements tells you to do, do a pkg uninstall readline and then do a simple rvm remove 1.9.3; rvm install 1.9.3
