Drupal installation on local Mac

when I tried the attached connect test script I got this:

Warning: mysql_connect() [function.mysql-connect]: [2002] No such file or directory (trying to connect via unix:///tmp/mysql.sock) in /Library/WebServer/Documents/drupal-6.15/connect-test.php on line 2

Warning: mysql_connect() [function.mysql-connect]: No such file or directory in /Library/WebServer/Documents/drupal-6.15/connect-test.php on line 2

<?php
$link = mysql_connect('localhost', 'name', 'name');
if (!$link) {
    die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql_close($link);
?>

I found: http://mike.eire.ca/2009/08/07/macports-upgrade-to-mysqlnd/ and added snippet to newly created my.cnf in /opt/local/etc/mysql5/ . But I still get the same errors installing Drupal:

Failed to connect to your MySQL database server. MySQL reports the following message: No such file or directory.

    * Are you sure you have the correct username and password?
    * Are you sure that you have typed the correct database hostname?
    * Are you sure that the database server is running?

For more help, see the Installation and upgrading handbook. If you are unsure what these terms mean you should probably contact your hosting provider.

Well tried again and this time I used 127.0.0.1 as localhost. Then I got the attached errors.

Here are the errors:

Anybody?

Found a sample .cnf file and followed its instructions:

You can copy this file to
# /opt/local/etc/mysql5/my.cnf to set global options,

No luck yet though....

# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M - 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# You can copy this file to
# /opt/local/etc/mysql5/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /opt/local/var/db/mysql5) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# The following options will be passed to all MySQL clients
[client]
#password	= your_password
port		= 3306
socket		= /opt/local/var/run/mysql5/mysqld.sock

# Here follows entries for some specific programs

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     =   <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>

@ scifikillr I have, but as I used a LAMP on Ubuntu I decided to use it on my Mac as well. The first installation of Drupal and Wordpress after the Installation of all needed elements and activation of Mac Ports was a breeze.
Now there seems to be a socket error. An error I never encountered before. Wordpress is fine but Drupal won't launch.
I need to figure this out so I can tackle these issues in the future and learn more about MySQL and Apache and a Mac. All help is greatly appreciated!

Solved the issue by myself. Installed Apache and PHP from mac Ports, adjusted php.ini's mysql sock and got everything running.

Thread sort of died while I got some help @ the Mac Ports Mail group and fixed the issue.
