# Install libxml2 using Homebrew
# If you don't have Homebrew, follow the instructions at:
# https://github.com/mxcl/homebrew/wiki/Installation
# -------------------------------------------------------
brew install libxml2

# Install libxslt from source code
# If you don't have wget, follow the instructions at:
# http://www.mactricksandtips.com/2008/07/installing-wget-on-your-mac-for-terminal.html
# Or use Homebrew:
# brew install wget
# -------------------------------------------------------------------------------------
wget ftp://xmlsoft.org/libxml2/libxslt-1.1.26.tar.gz
tar xvfz libxslt-1.1.26.tar.gz
cd libxslt-1.1.26
./configure --prefix=/usr/local/Cellar/libxslt/1.1.26 --with-libxml-prefix=/usr/local/Cellar/libxml2/2.7.8
make
sudo make install

# Install libiconv using Homebrew:
# --------------------------------
brew install libiconv
sudo brew link libiconv

# Install the Nokogiri gem passing in all the dependency paths:
# -------------------------------------------------------------
gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.7.8/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.7.8/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26 --with-iconv-include=/usr/local/Cellar/libiconv/1.14/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.14/lib

On a Mac Lion install with Apple's libiconv I was able to install libxslt-1.1.28 using brew and then the gem using

gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.9.1/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.1/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.28

Thanks for this writeup!

You should probably use the versions of these libraries that come with the system (that's why homebrew's removed libiconv now). On Mavericks, I just needed to xcode-select --install followed by a normal gem install nokogiri.

xcode-select --install is the missing key. 👍

+1 to xcode-select --install on Mavericks

Awesome!-- I couldn't get a Vagrant plugin to install relating to a Nokogiri error. followed this. Skipped the

make
sudo make install

# Install libiconv using Homebrew:
# --------------------------------
brew install libiconv
sudo brew link libiconv

Instructions. used xcode-select --install and sudo gem install nokogiri

Probably don't need more than xcode-select --install and sudo gem install nokogiri on Mavericks. Awesome!

+1 xcode-select --install was it! Thx a lot for that!

Thanks works for me as well!
