Ruby on Rails on Mac OS Lion MysqlCompat::MysqlRes Error

If you are running ruby in Mac OS X Lion and are having trouble with MySQL with the ever annoying message "uninitialized constant MysqlCompat::MysqlRes please do not spend the hours I did trying to solve it. Here is how to do it. The instructions below assume you have a 64 bits processor.

1. Make sure you have MySQL installed. You need to download it from http://dev.mysql.com/downloads/mysql/, choose any Mac OS X ver. for x86, 64-bit, DMG Archive for an Intel Mac. The easiest format is the .dmg file as it allows for an installation visually using the GUI and comes with a panel for the Preference Settings.
2. Now be sure that there are no mysql gems installed by running the command sudo gem uninstall mysql.
3. This seems to be the most important step for Mac OS Lion, as everything else is commonly tipped in every page with solutions to the MysqlCompat::MysqlRes Error. What you need to do is add the command "export DYLD_LIBRARY_PATH="/usr/local/mysql/lib:$DYLD_LIBRARY_PATH"" to your ~/.bash_profile. Reload your terminal screen or run source ~/.bash_profile.
4. Next step is installing and compiling with native directives the mysql gem. Here is the command "env ARCHFLAGS="-arch x86_64" sudo gem install mysql -- --with-mysql-dir=/usr/local/mysql --with-mysql-config=/usr/local/mysql/bin/mysql_config".

That's it! Happy developing!
