The error message I was treated to contained the following:

MacBook-Pro-de-Ethan-Garofolo:~ juanpaco$ sudo gem install thin
Password:
Building native extensions. This could take a while...
ERROR: Error installing thin:
ERROR: Failed to build gem native extension.

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb install thin
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h


Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/eventmachine-0.12.10 for inspection.
Results logged to /Library/Ruby/Gems/1.8/gems/eventmachine-0.12.10/ext/gem_make.out

The solution was hyper-intuitive. Install XCode. Because of course that's the first thing you think of.
