Installation error (I just @#~#@# can’t start!)

What can be happening?
I modified “config.php” with all the right data, ftp-ed them to my root directory, and then executed the famous “wp-admin/install.php”… And this message covered my screen: “Warning: Unknown(): open_basedir restriction in effect. File(/home/wrighton/public_html/wp-admin/install.php) is not within the allowed path(s): (/home/tenetor/:/usr/lib/php:/usr/local/lib/php:/nuting) in Unknown on line 0

Anybody can help me? THX in advance.
