Nokogiri on OS X 10.8

I know there's a ton of questions about this here on SO, but I really can't manage to install Nokogiri on my OS X 10.8.3 system.

I did the rituals:

brew install libxml2 libiconv libxslt
brew link --force libxml2 libiconv libxslt

but I keep getting these errors after doing a sudo gem install nokogiri:

Fetching: nokogiri-1.5.5.gem (100%)
Building native extensions.  This could take a while...
ERROR:  Error installing nokogiri:
    ERROR: Failed to build gem native extension.

    /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb

libiconv is missing.  please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

The interesting thing is that the libiconv error is randomly alternated with a libxml2 error. I followed the instructions at http://nokogiri.org/tutorials/installing_nokogiri.html but it just doesn't work.

Edit

I don't believe what just happened. Really, I don't.

brew uninstall libxml2 libiconv libxslt

It works now, gem installs it. It complained a little:

No definition for parse_memory

No definition for parse_file

No definition for parse_with

No definition for get_options

No definition for set_options
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rdoc/rdoc.rb:280: warning: conflicting chdir during another chdir block
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rdoc/rdoc.rb:287: warning: conflicting chdir during another chdir block

but at least in Middleman (that's were I'm using it) it works like a charm. Am I crazy?

What did actually work for me is this.

Brew

After you installed brew, install the following libs:

brew install libxml2 libxslt

RVM

Now, in bash (if you're on zsh, just issue bash to move to the bash shell) do:

curl -L https://get.rvm.io | bash -s stable --rails --autolibs=enabled

to get RVM (Ruby Version Manager). In your bash|zshrc, paste the following line:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

to load rvm on startup.

Note that if you didn't install the above libs with brew, the rvm installation will fail.

Restart the terminal and then issue:

rvm install 1.9.3 # or the version you like, 1.9.3 worked for nokogiri

And to use this version as the system default just issue:

rvm --default use 1.9.3

Install nokogiri via gem

Now the gem install nokogiri command should work fine.

Note that omitting the sudo is fundamental when dealing with rvm and gem stuff. That's one of the things that I missed and made me go crazy.
