solaris9上启动mysql (errno: 13) 如何解决？

cnhero

solaris9上使用SOL软件包mysql-3.23.53-sol9-sparc-local 新安装的 mysql
已经运行了 mysql_install_db，却无法启动进程：
#safe_mysqld &
[1] 264
[root@mail /usr/local/mysql]#Starting mysqld daemon with databases from /usr/local/mysql/var
050805 10:47:02  mysqld ended


[1]+  Done                    bin/safe_mysqld

#cat var/mail.err
050805 10:24:42  mysqld started
050805 10:24:43  /usr/local/mysql/libexec/mysqld: Table 'mysql.host' doesn't exist
050805 10:24:43  /usr/local/mysql/libexec/mysqld: Normal shutdown

050805 10:24:43  mysqld ended

050805 10:35:24  mysqld started
050805 10:35:25  /usr/local/mysql/libexec/mysqld: Can't find file: './mysql/host.frm' (errno: 13)
050805 10:35:25  /usr/local/mysql/libexec/mysqld: Normal shutdown

050805 10:35:25  mysqld ended

什么原因呢？如何解决呢？
