MySQL user does not need and should not have a login shell.
the entry in the password and group file should be set-up
automatically for you when you install MySQL.

The method I used to install MySQL was to use the ports
system via portupgrade.  Then run mysql_install_db
--user=mysql
This sets a lot of things up for you.

As I believe another poster has mentioned you will want to
delete
everything under /var/db/mysql/

Also do a chown mysql:mysql /var/db/mysql

Read the chapters in the MySQL manual regarding post-install
tasks under UNIX and securing the initial MySQL accounts.

Hope this helps,
