I'm trying to setup Nginx+phpFPM for first time (php5.2) and can't get it working. Base system is FreeBSD 9.1.
So my main configs:

nginx.conf - http://pastebin.com/KwhHr0NK
php-fpm.conf - http://pastebin.com/KQBwp3KL
vhost config - http://pastebin.com/qyFzc9Xa

Nginx started and working as i may see output from phpinfo(), but if i put something comlex, eg. CMS like Drupal, WP, Joomla it generates HTTP 500 error.

Also I can't see any php errors in logs despite they are defined in php-fpm.conf
