OS X Mavericks, Cannot install libxml-ruby gem?-Collection of common programming errors
On a clean install of Mac OS 10.9, jumping from 10.7.5, I seem incapable of installing the libxml-ruby gem. I use Homebrew and RVM to manage my environment, and I’ve installed the following things:
brew list
apple-gcc42 gcc46 libmpc08 mpfr2 postgresql
autoconf gmp4 libtool mysql55 ppl011
automake libgpg-error libxml2 openssl readline
cloog-ppl015 libiconv libxslt ossp-uuid wget
cmake libksba libyaml pkg-config
Entering brew doctor returns:
Your system is ready to brew.
Running bundle install yields the following, where I’ve removed the links. I can’t post more than two without 10 reputation apparently:

Gem files will remain installed in /Users/iandonovan/.rvm/gems/ruby-1.9.3-p392@standard-set/gems/libxml-ruby-2.3.3 for inspection.
Results logged to /Users/iandonovan/.rvm/gems/ruby-1.9.3-p392@standard-set/gems/libxml-ruby-2.3.3/ext/libxml/gem_make.out
An error occurred while installing libxml-ruby (2.3.3), and Bundler cannot continue
Make sure that `gem install libxml-ruby -v '2.3.3'` succeeds before bundling.
Running that standalone gem install, gem install libxml-ruby -v '2.3.3', returns the same error message.
XCode 5.0.1 is installed, alongside the developer tools. I could not install the dev tools through xcode-select --install because of “A network problem” (according to the dialog box) and instead downloaded the Mavericks package from developer.apple.com.
Has anyone else dealt with this? Nokogiri appears to be installing just fine (1.5.9 gets bundled), but libxml-ruby can’t finish.
