I'm running Leopard (10.5.8) on a Macbook (not Pro) and I had MySQL running ok, but the Preferences pane wasn't working. I thought a fresh install would be a good idea, so I went through the uninstall process described here:

... which consisted of removing a bunch of files like this:

sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
vim /etc/hostconfig and removed the line MYSQLCOM=-YES-
rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*

But now when I try and install mysql-5.5.20-osx10.5-x86.pkg

I get this:

The following install step failed run postflight script for mysql 5.5.20-community for Mac OS X. Contact the software manufacturer for assistance.

mysql is there, after each failed install, but all my attempts to use it get the same error msg:

$ mysql -u root -p
dyld: unknown required load command 0x80000022

What can I do?

In the first link you referenced, there was one command missing, Ben Alpert answered with this reply.

$ sudo rm -rf /var/db/receipts/com.mysql.*
