请教mysql数据库启动错误提示问题？？？

俺用的mysql直接解压就可以用了，不用编译的，版本是：mysql-4.0.13.tar.gz

俺是创建mysql用户，启动数据库的时候提示如下错误：
再执行这个语句：/usr/local/mysql/bin/mysqld_safe --user=mysql &
显示如下：
[1] 24154
[root@localhost bin]# The file /usr/local/mysql/libexec/mysqld doesn't exist or is not

executable
Please do a cd to the mysql installation directory and restart
this script from there as follows:
./bin/mysqld_safe.

查看错误日志提示如下：

/usr/local/mysql/bin/mysqld: ERROR: unknown option '--log-bin # required for replication'
031012 10:00:04 mysqld ended


到底是什么原因呢？
