I've followed the instructions on http://geryit.com/blog/2011/01/installing-mysql-with-rails-on-mac-os-x-snow-leopard/ , including the installation of ruby via macport.
Whenever I execute gem install mysql , I'll get the following error
bash-3.2# gem install mysql
Building native extensions. This could take a while...
ERROR: Error installing mysql:

How can I resolve this issue ? I've installed the 32-bit mysql using the package file (.pkg) and also, I'm extremely new to ruby...
Update 4/26/11 5:11pm EST
Installed RVM and updated ruby to 1.9.2
Also I have looked through the links posted on the comments. I did locate mysql_config
and results were
/usr/local/mysql-5.1.56-osx10.6-x86/bin/mysql_config
/usr/local/mysql-5.1.56-osx10.6-x86/man/man1/mysql_config.1
Hence, I tried
gem install mysql - -with-mysql-config=/usr/local/mysql-5.1.56-osx10.6-x86/bin/mysql_config
but it still doesn't work... I did get new error information however..

You have to install development tools first.

Really wish to thank those who commented... and really appreciate if more help can be given..... been trying to get the darn mysql installed for 2 days...
The program 'mysql_config' is currently not installed. You can install it by typing:
$ sudo apt-get install libmysqlclient-dev
$ bundle install
bundle show [mysql2] # To find the location.
Try this:
gem install mysql -- --with-mysql-config=/usr/local/mysql-5.1.56-osx10.6-x86/bin/mysql_config
(Note the extra dashes)
If that doesn't work, I highly recommend going with the homebrew installation mentioned above of MySQL. You can read about a soup-to-nuts installation here: Uninstall Ruby on Rails on Mac OS X 10.6
I had the same issue in Cent OS, but got it resolved by installing mysql-devel
yum install mysql mysql-server mysql-devel
