Summary:
On OS X Mavericks DP7 with Xcode5-DP6, I am running an Octopress site. It relies on Ruby gems and uses Ruby Bundler to install them (Not necessary to reproduce error, just setting the stage). When installing gems that require native extensions, get the following error:
---

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Tested with RedCloth gem, pg gem and bson_ext gem, all the same error.

It seems that the include and lib folders needed for compiling ruby native extensions are missing in OS X Mavericks.

Steps to Reproduce:
1. Install Xcode5-DP6 on Mavericks (needed to compile native extensions)
2. Check Ruby version (ruby 2.0.0p247 (2013-06-27 revision 41674) [universal.x86_64-darwin13])
3. sudo gem install RedCloth (or sudo gem install bson_ext)



Expected Results:
On OS X 10.8 and before, it compiles and installs the gem, no problems.

Actual Results:
Fetching: bson-1.9.2.gem (100%)
Successfully installed bson-1.9.2
Fetching: bson_ext-1.9.2.gem (100%)

Version:
OS X 10.9 13A569

Notes:
Since a lot of OS X Users work with ruby, I think this is a big issue.

FYI using `rbenv` from home-brew works around the issue, but it's not for the faint hearted.
