Dolphin not working in Sub Domain

hey,
this is somethign tricky
i tried installing dolphin in a sub directory and it got installed perfectly
but when i create a sub domain and try to install in it.. it gives me

Warning: require_once(/home/content/g/l/o/xyz/html/ray/modules/global/inc/header.inc.php) [function.require-once]: failed to open stream: No such file or directory in /home/content/g/l/o/xyz/html/abc/inc/header.inc.php on line 172

Fatal error: require_once() [function.require]: Failed opening required '/home/content/g/l/o/xyz/html/ray/modules/global/inc/header.inc.php' (include_path='.:/usr/local/php5/lib/php') in /home/content/g/l/o/xyz/html/abcx/inc/header.inc.php on line 172


i tried this thrice... with dirrect sub domains and different database,
What should i do?
xyz and abc in url above are replicated names.
