How do you uninstall MySQL from Mac OS X?

I accidentally installed the PowerPC version of MySQL on my Intel Mac in Snow Leopard, and it installed without a problem but of course doesn't run properly. I just didn't pay enough attention. Now when I try to install the correct x86 version it says that it can't install because a newer version is already installed. A Google query led me to perform these actions/delete these files to uninstall it:

sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/MySQL*
rm -rf ~/Library/PreferencePanes/MySQL*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*

And finally removed the line MYSQLCOM=-YES- from /etc/hostconfig

They haven't seemed to help at all. I am still receiving the same message about there being a newer version. I tried installing an even newer version (the current Beta) and it also gave me the same message about a newer version already being installed. I can't uninstall it from the Prefs Pane because I never installed the PrefPane also.

Aside from the long list of remove commands in your question, which seems quite comprehensive in my recent experience of exactly this issue, I found mysql.sock running in /private/var and removed that. I used

find / -name mysql -print 2> /dev/null

...to find anything that looked like a mysql directory or file and removed most of what came up (aside from Perl/Python access modules). You may also need to check that the daemon is not still running using Activity Monitor (or at the command line using ps -A). I found that mysqld was still running even after deleting the files.

It might be overkill but your MySQL command history can also be wiped from:

~/.mysql_history
