"rvm install ree" fails on ubuntu: how to get pass openssl and zlib dev headers requirement?

I want to install Ruby Entreprise Edition via rvm on Ubuntu. I'm running the following:

$ rvm install ree --with-readline-dir=/home/ubuntu/.rvm/usr --with-iconv-dir=/home/ubuntu/.rvm/usr --with-zlib-dir=/home/ubuntu/.rvm/usr --with-openssl-dir=/home/ubuntu/.rvm/usr

However, it fails with the following error:

Some required software is not installed.
But don't worry, this installer will tell you how to install them.
Press Enter to continue, or Ctrl-C to abort.
--------------------------------------------
Installation instructions for required software

 * To install OpenSSL development headers:
   Please download it from http://www.openssl.org/

 * To install GNU Readline development headers:
   Please download it from http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html

However I do have openssl, readline, and zlib-devel installed both as rvm package and via apt-get on the system.

$ rvm package install ree_dependencies

Please help!

If you use rvm version 1.9.0,

$ rvm package install ree_dependencies ERROR: Unrecognized command line argument: 'package' ( see: 'rvm usage' )

Using

$ rvm pkg install ree_dependencies

will work

It may be slightly different depending on which version of Ubuntu you are rocking, but an apt-get install libssl-dev libreadline-dev should get those headers installed.

Actually, the problem was that I was under "rvm jruby-1.6.2" when running install. It seems like when you are under jruby some scripts get messed up. So this is my solution:

rvm use system
rvm package install ree_dependencies
rvm install ree --with-readline-dir=/home/ubuntu/.rvm/usr  \
                --with-iconv-dir=/home/ubuntu/.rvm/usr     \
                --with-zlib-dir=/home/ubuntu/.rvm/usr      \
                --with-openssl-dir=/home/ubuntu/.rvm/usr
