Newbie in trouble.

[admin]

I'm running PHP4 and mySql (both installed from source) on RH7.
I'm using this little test script
<?php
$link = mysql_connect
or die ("Could not connect");
print ("Connected successfully");
if (mysql_create_db ("my_db")) {
print ("Database created successfully\n");
} else {
printf ("Error creating database: %s\n", mysql_error ());
}
?>
And I get this in response.
Connected successfully
Fatal error: Call to undefined function: mysql_create_db() in /var/www/sensei/htdocs/phpMyAdmin/test1.php3 on line 5

Any help would be appreciated...
Thanx in advance.
