Accidentally installed mysql twice

First with the typical .DMG installation, and the second with the Brew.

I was getting a .sock error with the Brew installation, so I uninstalled it with brew uninstall mysql

And now when I try to use the original mysql I get this

uninitialized constant MysqlCompat::MysqlRes

Yikes. I completely removed mysql and anything related to it as so :

sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -开发者_开发百科rf /var/db/receipts/com.mysql.*

Then I redownloaded it, ( tried this twice with both 5.5 and 5.1 ), and installed it, used arch flags for my 64 bit mac os x macbook pro.

sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/mysql_config

And I got the same error:

uninitialized constant MysqlCompat::MysqlRes

Anyone know what could possibly going wrong here? Is there something remote that I didn't delete yet?

This error effects so many Rails users, that's why its here on StackOverflow.com.

Here's the issue. MySQL 5.5.9 does not work with the latest mysql gem 2.8.1

You must install the MySQL Library 5.5.1 as of 2/24/2011.

And following the uninstall directions above. I used this as my archflags installation :

env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql-5.1.55-osx10.6-x86_64/bin/mysql_config
