Failed install on Mac OS X (no replies)

OS X version: 10.6.8
Mysql version: mysql-5.5.20-osx10.6-x86_64

Installation fails -- I'm guessing because I had an earlier version installed, and have not removed every possible artifact. I've scoured the web and tried everything I've found, but without success yet. Here is a list of what I have done:


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 /var/db/receipts/com.mysql.mysql*
sudo rm /private/var/db/receipts/com.mysql*
sudo rm /etc/my.cnf
sudo rm -rf /var/db/receipts/com.mysql.*
sudo rm -rf /var/db/receipts/com.mysql.mysql*
sudo rm /private/var/db/receipts/com.mysql.mysql.plist
sudo rm /private/var/db/receipts/com.mysql.mysql.bom
sudo rm /var/db/dslocal/nodes/Default/groups/_mysql.plist
sudo rm /var/db/dslocal/nodes/Default/users/_mysql.plist
sudo rm /var/db/receipts/com.mysql.mysql.bom
sudo rm /var/db/receipts/com.mysql.mysql.plist


Is there anything else I am missing?

Thanks for any suggestions...
Bill
