There's a $mysql_socket rc.conf variable you need to set as well.

(Although if /usr/tmp is set to mode 1777, what's the benefit of using that
location rather than the default /tmp/mysql.sock ?)

Is this the only my.cnf file on the system?  There are several places
where MySQL will pick up a my.cnf file: directly from the mysql_dbdir
or /usr/local/etc/my.cnf [The rc.d/mysql-server script automatically
adds ${mysql_dbdir}/my.cnf to the list of locations]

Judging by the complaints about 'update log no longer supported' I'm
guessing that there is somewhere a my.cnf or a .my.cnf file filled with
configuration settings appropriate to a much earlier version of MySQL.
A good strategy is to grab one of the sample .cnf files from
/usr/local/share/mysql (according to the capabilities of your server)
copy that into ${mysql_dbdir}/my.cnf and edit to make any local
