mysql的配置启动问题,谢谢帮忙

我用的是中文的rh9.
我down的mysql是mysql-standard-5.0.0-alpha-pc-linux-i686.tar.gz

解压到/usr/local/mysql
cd mysql
./configuge -prefix=/usr/local/mysql
添加用户usradd mysql
./bin/mysqld_safe

运行提示
Starting mysqld daemon with databases from /usr/local/mysql/data
040831 00:10:29  mysqld ended

我用mysql/sql-bench/run_all_tests
运行提示
can't locate DBI.pm 等,,

我从网上找了好多文档,照做也是一样,
一晚上也没配好,哪位告诉我正确的步骤,谢了.      
建库了吗?
#/usr/local/mysql/bin/mysql_install_db
