Installation of Mysql

I posted this in the sqlforumn and they told me to come here. please help.

I'm trying to intall mysql on a mac with these commands

shell> groupadd mysql
shell> useradd -g mysql mysql
shell> cd /usr/local
shell> gunzip < /PATH/TO/MYSQL-VERSION-OS.tar.gz | tar xvf -
shell> ln -s FULL-PATH-TO-MYSQL-VERSION-OS mysql
shell> cd mysql
shell> chown -R mysql .
shell> chgrp -R mysql .
shell> scripts/mysql_install_db --user=mysql
shell> chown -R root .
shell> chown -R mysql data
shell> bin/mysqld_safe --user=mysql &

These commands are from the README and i did dl the correction verion. For starters, the first two don't work at all, any help please?

Please don't cross-post, it wastes everybodies time by getting three or four people to answer the same question. Continue discussion here.
