Can't fix 'bundle install' failing for gems with native extensions

I am deploying Ruby On Rails apps on an Amazon EC2 cloud server. The server is running on Amazon Linux alami-2011.02. I can't say the distro it's based on (from my search, RedHat/CentOS, but I'm newbie in that field).

I've installed my Ruby environment with RVM (installed as root). I've setup two rubies:

For each Rails app I deploy, I create a separate RVM gemset.

Since I ran in this problem, I've refreshed completely the Ruby environment by running rvm implode.

Here are my environment versions:

ruby -v      ---> ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux]
rvm -v       ---> 1.8.1
gem -v       ---> 1.6.2
bundle -v    ---> Bundler version 1.0.18

After this rvm implode:

This is what I get know when performing bundle install (logged in as root):

Updating https://github.com/p7r/will_paginate.git
Fetching source index for http://rubygems.org/
Installing rake (0.9.2) 
Installing multi_json (1.0.3) 
Installing activesupport (3.1.0) 
Installing bcrypt-ruby (3.0.0) with native extensions /usr/local/rvm/scripts/rvm/rubies/ruby-1.9.2-p290/lib/ruby/site_ruby/1.9.1/rubygems/installer.rb:552:in `rescue in block in build_extensions': ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError)

        /usr/local/rvm/scripts/rvm/rubies/ruby-1.9.2-p290/bin/ruby extconf.rb 

Gem files will remain installed in /usr/local/rvm/scripts/rvm/gems/ruby-1.9.2-p290@app/gems/bcrypt-ruby-3.0.0 for inspection.
Results logged to /usr/local/rvm/scripts/rvm/gems/ruby-1.9.2-p290@app/gems/bcrypt-ruby-3.0.0/ext/mri/gem_make.out

    [ removed the backtrace ]

However, if i just use gem install bcrypt, the gem install correctly, and I can just use bundle install which will run until the next gem with native extensions...

I've had the same issue with a ruby-1.9.2-p180 install, I tried downgrading RubyGems to different versions until 1.5.3, I imploded my RVM... I've looked a lot on the web for answers, this problem seems recurrent, but nothing worked for me.

Thanks in advance for your help!

This might be due to insufficient memory for compiling the native extensions. In my experience, bundle install is more memory intensive than simply using gem install. Take a look at /var/log/messages and see if any such issues are present. Also, use top to identify any heavyweight processes, like colleagues leaving rails console running in a screen session. ;)

If you are running on linux you need to install libraries/packages before install bcrypt-ruby gem.

sudo apt-get install ruby1.8-dev //for ruby 1.8.7

or

sudo apt-get install ruby-dev

or

sudo apt-get install ruby1.9-dev //for ruby 1.9.2

now you can install bcrypt-ruby gem with following command

sudo gem install bcrypt-ruby
