"No such file or directory" error when installing 1.9.0-rc.1

For 1.9.0 rc1, I follow instructions on http://learn.elgg.org/en/latest/intro/install.html but when I come to "visit your elgg site" step, I am getting the following error:


Warning: include_once(/srv/../www/sub.mySite.com/engine/settings.php): failed to open stream: No such file or directory in /srv/../www/sub.mySite.com/engine/start.php on line 51
Warning: include_once(): Failed opening '/srv/../www/sub.mySite.com/engine/settings.php' for inclusion (include_path='.:/usr/local/php-5.4.28/share/pear') in /srv/../sub.mySite.com/engine/start.php on line 51
Warning: Cannot modify header information - headers already sent by (output started at /srv/../www/sub.mySite.com/engine/start.php:51) in /srv/../www/sub.mySite.com.com/engine/start.php on line 52


When I try the same thing with Elgg 1.8.19, it displays the first screen of installation process.

What is going wrong in 1.9.0 rc1?
