Can't fix PHP Fatal error: Class 'MongoPool' not found - mongodb

Question

Unfortunately I'm unable to fix Class 'MongoPool' not found error. Rechecked everything in configs and everything looks normal to me :( Spent 4 hours on this already :(
I'm using:
Ubuntu 12.04
nginx 1.1.19
php 5.3.10-1ubuntu3.4 as php-fpm extension to nginx
mongodb driver 1.3.0RC1-dev
Configuration info:
my phpinfo() output is here
nginx.conf is here
fastcgi_params is here
php.ini is here
php-fpm.conf is here
mongo.ini in php folder is this
extension=mongo.so
mongo.native_long = true
mongo.utf8 = 1
/etc/php5/fpm/pool.d/www.conf is pretty short too
[www]
user = www-data
group = www-data
listen = /var/run/php-fpm.sock
pm = dynamic
pm.max_children = 10
pm.start_servers = 4
pm.min_spare_servers = 2
pm.max_spare_servers = 6
access.log = /var/www/log/$pool.access.log
;chroot = /var/www/
chdir = /
Could you please take a look at my configs and help me ?
Test page is this
<?php
MongoPool::setSize(2);
?>
nginx server's config is
server {
root /usr/share/nginx/www;
index index.php index.html index.htm;
server_name localhost 192.168.1.149;
location / {
try_files $uri $uri/ /index.html;
}
location /doc/ {
alias /usr/share/doc/;
autoindex on;
allow 127.0.0.1;
deny all;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}
}
Log snippet from nginx

Answer 1

As user eicto hinted above creators of MongoDb Driver for PHP removed this class from trunk version of the driver about 2 months ago (see this commit).
We will be adding back MongoPool and couple of the other methods for backwards compatibility, but they won't do anything and just issue E_DEPRECATED warning
Take care when using development versions.
