Brew install mysql on snow leopard not quite working

I installed mysql via brew, it looks like the installation went fine. Mysql will not allow me to set a root password, even if it becomes difficult for me. It looks like tables are missing at all. Detailed conclusion below.

jb:~ jb$ brew install mysql

==> Caveats
Set up databases with:
    unset TMPDIR
    mysql_install_db

If this is your first install, automatically load on login with:
    mkdir -p ~/Library/LaunchAgents
    cp /usr/local/Cellar/mysql/5.1.55/com.mysql.mysqld.plist ~/Library/LaunchAgents/
    launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist

If this is an upgrade and you already have the com.mysql.mysqld.plist loaded:
    launchctl unload -w ~/Library/LaunchAgents/com.mysql.mysqld.plist
    cp /usr/local/Cellar/mysql/5.1.55/com.mysql.mysqld.plist ~/Library/LaunchAgents/
    launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist

Note on upgrading:
    We overwrite any existing com.mysql.mysqld.plist in ~/Library/LaunchAgents
    if we are upgrading because previous versions of this brew created the
    plist with a version specific program argument.

Or start manually with:
    mysql.server start

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/local/Cellar/mysql/5.1.55/bin/mysqladmin -u root password 'new-password'
/usr/local/Cellar/mysql/5.1.55/bin/mysqladmin -u root -h jb.local password 'new-password'

Alternatively you can run:
/usr/local/Cellar/mysql/5.1.55/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr/local/Cellar/mysql/5.1.55 ; /usr/local/Cellar/mysql/5.1.55/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/local/Cellar/mysql/5.1.55/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/local/Cellar/mysql/5.1.55/bin/mysqlbug script!

jb:~ jb$ cp /usr/local/Cellar/mysql/5.1.55/com.mysql.mysqld.plist ~/Library/LaunchAgents/
jb:~ jb$ launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist
jb:~ jb$ /usr/local/Cellar/mysql/5.1.55/bin/mysql_secure_installation




NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!


In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

SAFETY SUPPORT ...

I made sure that I have usr / local:

jb:~ jb$ sudo chown -R `whoami` /usr/local
jb:~ jb$ which mysql
/usr/local/bin/mysql

I even tried running mysql with "skip grant tables" and setting a password:

jb:~ jb$ launchctl unload -w ~/Library/LaunchAgents/com.mysql.mysqld.plist
jb:~ jb$ killall mysqld
No matching processes belonging to you were found
jb:~ jb$ mysqld_safe --skip-grant-tables
110314 15:09:01 mysqld_safe Logging to '/usr/local/var/mysql/jb.local.err'.
110314 15:09:01 mysqld_safe Starting mysqld daemon with databases from /usr/local/var/mysql

Then in another terminal window:

jb:~ jb$ mysql -u root

What the hell shouldn't affect the series? Does it look like tables are not made? Should I run mysql_install_dbusing sudo?
