Install trouble, please help, errors listed below

Hi there
I tried to do my first WP installation. Didnt work, even the available instructions were good and plenty were available.

What I have done so far:
registered domain
set up a hosting account
created a database
uploaded files (twice , 1st to subdirectory, once that pancaked, directly to root)

I keep getting the folllowing error msgs when I go to url
https://www.birchbolete.com/wp-admin/install.php

errors listed:

Warning: Unknown(): open_basedir restriction in effect. File(/home/tatti/public_html/wp-admin/install.php) is not within the allowed path(s): (/home/wwwbirc:/usr/lib/php:/usr/local/lib/php:/tmp) in Unknown on line 0

Warning: Unknown(/home/tatti/public_html/wp-admin/install.php): failed to open stream: Operation not permitted in Unknown on line 0

Warning: (null)() [function.include]: Failed opening ‘/home/tatti/public_html/wp-admin/install.php’ for inclusion (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in Unknown on line 0

my wp-confiog.php looks like this:
<?php
// ** MySQL settings ** //
define(‘DB_NAME’, ‘tatti_tiamaria’); // The name of the database
define(‘DB_USER’, ‘tatti_tiko’); // Your MySQL username
define(‘DB_PASSWORD’, ‘tikojapiki’); // …and password
define(‘DB_HOST’, ‘localhost’); // 99% chance you won’t need to change this value
define(‘DB_CHARSET’, ‘utf8’);
define(‘DB_COLLATE’, ”);

// You can have multiple installations in one database if you give each a unique prefix
$table_prefix = ‘wp_’; // Only numbers, letters, and underscores please!

// Change this to localize WordPress. A corresponding MO file for the
// chosen language must be installed to wp-content/languages.
// For example, install de.mo to wp-content/languages and set WPLANG to ‘de’
// to enable German language support.
define (‘WPLANG’, ”);

/* That’s all, stop editing! Happy blogging. */

define(‘ABSPATH’, dirname(__FILE__).’/’);
require_once(ABSPATH.’wp-settings.php’);
?>

my database (from cpanel) info looks like this:
Current Databases:
tatti_tiamaria

Users in tiamaria
tatti_tiko (Privileges: ALL PRIVILEGES)

Connection Strings
Perl $dbh = DBI->connect(“DBI:mysql:tatti_tiamaria:localhost”,”tatti_tiko”,”<PASSWORD HERE>”);
PHP $dbh=mysql_connect (“localhost”, “tatti_tiko”, “<PASSWORD HERE>”) or die (‘I cannot connect to the database because: ‘ . mysql_error());
mysql_select_db (“tatti_tiamaria”);

Any ideas on where to start with this mess?
I recently did a site with joomla. Joomla had a .php file you could upload and run, to check all files were present, any similar diagnostics tools available for wordpresss.

Please help I am itching to start blogging.

thanks
