Installation of system tables failed! 
Examine the logs in /var/lib/MySQL5 for more information. 
You can try to start the MySQLd daemon with: 
/usr/local/MySQL5/libexec/MySQLd –skip-grant & 
and use the command line tool 
/usr/local/MySQL5/bin/MySQL to connect to the MySQL 
database and look at the grant tables: 
http://www.knowsky.com/ 
shell> /usr/local/MySQL5/bin/MySQL -u root MySQL 
MySQL> show tables 
Try ‘MySQLd –help’ if you have problems with paths. Using –log 
gives you a log in /var/lib/MySQL5 that may be helpful. 
The latest information about MySQL is available on the web at

Please consult the MySQL manual section: ‘Problems running MySQL_install_db’, 
and the manual section that describes problems on your OS.

Please check all of the above before mailing us! 
And if you do mail us, you MUST use the /usr/local/MySQL5/bin/MySQLbug script!
