Failing to bundle install tiny_tds on Mac OS X 10.8 with Homebrew FreeTds

MY QUESTION
What are some surefire steps I can take to 100% get this working?I would need real instructions, not one liner answers or vague conceptual descriptions of the process.

Let's get to the bottom of this.It would appear that there are conflicts somewhere and I've had subpar assistance from the gem developer on GitHub in relation to my experience with Ruby / Rails / Bundler / Homebrew so it's not completely their fault :PBut I need to figure out how to get this working ASAP so here goes with my current state of this problem.

UPDATE: 2/25/2013
Updated GCC / XCODE Version 4.6 (4H127) and downloaded latest version of XCODE COMMAND-LINE TOOLSand now iconv_open() is showing up in the extconf checker.Now I'm getting these errors:

I believe they are now issues with tiny_tds and compatibility with latest xcode paths.

Now I'm back to square one... iconv_open() not found when checked with `extconf.rb`

UPDATE 2: 2/25/2013
OKAY, so I reinstalled everything, Ruby / Rails / etc.And used some advice from a commenter to use ":path =>"and here is my output now when I run rails s

THINGS I'VE TRIED

1.) The initial EASY setup instructions like any other...

$ rails new test_app$ cd test_app

Now add these lines to Gemfile

gem 'tiny_tds'gem 'activerecord-sqlserver-adapter'

Now continue commands...

2.) IMAGINARY SUCCESS / FAKE IT TIL YOU MAKE IT / A BIG LET DOWN / ADVANCED SETUP INSTRUCTIONS
Found this blog entry...http://talltroym.blogspot.com/2012/04/installing-activerecord-sqlserver.html

I then located my correct paths to the libiconv library and the freetds library.Next, I ran it like this:

$ sudo gem install tiny_tds -- --with-iconv-include=/usr/local/Cellar/libiconv/1.14/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.14/lib --with-freetds-lib=/usr/local/Cellar/freetds/0.91/lib --with-freetds-include=/usr/local/Cellar/freetds/0.91/includePassword:Building native extensions.  This could take a while...Successfully installed tiny_tds-0.5.11 gem installedInstalling ri documentation for tiny_tds-0.5.1...Installing RDoc documentation for tiny_tds-0.5.1...

Tried bundle_install again, and shock... it still isn't installing via gem 'tiny_tds' in Gemfile...

So I remove tiny_tds from Gemfile and proceed to start the server up anyway...And as expected...

$ rails s=> Booting WEBrick=> Rails 3.2.12 application starting in development on http://0.0.0.0:3000=> Call with -d to detach=> Ctrl-C to shutdown serverExiting/usr/local/Cellar/ruby/1.9.3-p194/lib/ruby/gems/1.9.1/gems/gems/activesupport-3.2.12/lib/active_support/dependencies.rb:251:in `require': cannot load such file -- tiny_tds (LoadError)...

3.) MINI PORTILE

$ sudo gem install mini_portile$ sudo gem install rakecompiler$ rake TINYTDS_FREETDS_VERSION="current"Could not find gem 'tiny_tds (>= 0) ruby' in the gems available on this machine.Run `bundle install` to install missing gems.
