MySQL - The Installation Failed on Snow Leopard

I had an old instalation of MySQL but it wasn't working very well.. so i googled how to completley remove it and found this:

http://tomkeur.net/39/how-to-remove-mysql-completely-mac-os-x-leopard.html

and then did:

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

And now i'm getting this on a new install:

i also ran this commands:

    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

any help on this?

Many Thanks, Mr. Nizzle.

From the error log you posted, the failure is here:

/postflight: chown: mysql: Invalid argument

There are lots of reports of this error; its usual cause is the lack of a mysql user name. There is a duplicate of this question here with a solution to follow here.
