Installation of system tables failed!  Examine the logs in
/usr/local/Cellar/mysql/5.5.10/data/ for more information.

You can try to start the mysqld daemon with:

    shell> /usr/local/Cellar/mysql/5.5.10/bin/mysqld --skip-grant &

and use the command line tool /usr/local/Cellar/mysql/5.5.10/bin/mysql
to connect to the mysql database and look at the grant tables:

    shell> /usr/local/Cellar/mysql/5.5.10/bin/mysql -u root mysql
    mysql> show tables

Try 'mysqld --help' if you have problems with paths.  Using --log
gives you a log in /usr/local/Cellar/mysql/5.5.10/data/ that may be helpful.

Please consult the MySQL manual section
'Problems running mysql_install_db', and the manual section that
