Ok, I just got finished running the b2install.php and it says it was successful and to login. So, I renames the b2install.php file to installb2.php like it recommended in the readme.html file. When I tried to access the b2login.php file I get this error:

Fatal error: Call to undefined function: get_userdatabylogin() in /home/gocha2/www/www/b2/b2login.php on line 280

this is line 280 on the b2login page:
$userdata = get_userdatabylogin($user_login);

and I don't know what to do x.x;
please help... ;.;
