RoR, OS X, MySQL problem

[Ivan]

Zdravo svima,

Instalirao sam na mac mini serveru (10.7.4):

- Apache 2.2.22
- Ruby 1.8.7
- Rails 3.2.8
- mod_passenger 3.0.17
- MySQL 5.5.27

I imam jednu custom aplikaciju koju kada probam da instaliram sa "bundle install" dobijem gresku:

Installing mysql2 (0.3.11) with native extensions
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb --with-mysql-config=/usr/local/Cellar/mysql/5.5.27/bin/mysql_config

mysql.h is missing. please check your installation of mysql and try again.

*** 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.

Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib

--with-make-prog
--without-make-prog
--srcdir=.
--curdir
--ruby=/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
--with-mysql-config


Gem files will remain installed in /Users/admin/.bundler/tmp/40325/gems/mysql2-0.3.11 for inspection.
Results logged to /Users/admin/.bundler/tmp/40325/gems/mysql2-0.3.11/ext/mysql2/gem_make.out

An error occurred while installing mysql2 (0.3.11), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.11'` succeeds before bundling.

Probao sam sve moguce predloge sa Google ali nisam uspeo da namestim. Jel moze pomoc?
