问题
After working through the RVM setup, rspec and guard sections of chapter 3 of the Ruby on Rails Tutorial, whenever I run bundle install I get the following error dump:
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
/usr/bin/ruby1.9.1 extconf.rb
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError)
from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from extconf.rb:5:in `<main>'
Gem files will remain installed in /home/dan/.bundler/tmp/17577/gems/nokogiri-1.5.2 for inspection.
Results logged to /home/dan/.bundler/tmp/17577/gems/nokogiri-1.5.2/ext/nokogiri/gem_make.out
An error occured while installing nokogiri (1.5.2), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.5.2'` succeeds before bundling.
In the gem_make.out:
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
/usr/bin/ruby1.9.1 extconf.rb
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file --mkmf (LoadError)
from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from extconf.rb:5:in `<main>'
I've been debugging for a while now and I think I'm stuck. Help would be GREATLY appreciated!

You need the header files for compiling extension modules for Ruby.
You can get the proper version for your version of ruby with:
sudo aptitude install ruby-dev
