run check_configuration.php in the web browser: http://localhost/check_configuration.php and it threw the following result:

To fix the first warning, install PDO package for PHP 5 on ubuntu:

sudo apt-get install libmysqlclient15-dev
sudo pecl install pdo

then got the following message:

downloading PDO-1.0.3.tgz ...
Starting to download PDO-1.0.3.tgz (52,613 bytes)
.............done: 52,613 bytes
12 source files, building
running: phpize
sh: phpize: not found
ERROR: `phpize' failed

googled around and found out that need to install php5-dev version, so here we go:

sudo apt-get install php5-dev
sudo pecl install pdo

at the end of the installation, it displayed:

Build process completed successfully
Installing '/usr/include/php/ext/pdo/php_pdo.h'
Installing '/usr/include/php/ext/pdo/php_pdo_driver.h'
Installing '/usr/lib/php5/20060613/pdo.so'
install ok: channel://pecl.php.net/PDO-1.0.3
configuration option "php_ini" is not set to php.ini location
You should add "extension=pdo.so" to php.ini

sudo pecl install pdo_mysql

at the end of installation, it displayed:

Build process completed successfully
Installing '/usr/lib/php5/20060613/pdo_mysql.so'
install ok: channel://pecl.php.net/PDO_MYSQL-1.0.2
configuration option "php_ini" is not set to php.ini location
You should add "extension=pdo_mysql.so" to php.ini

edit php.ini at /etc/php5/apache2/ to add the above 2 lines, restart apache: sudo /etc/init.d/apache2 restart
and check the configuration again in the browser, boo! the first warning is gone!  so far so cool :)

sudo apt-get install php5-xsl
sudo /etc/init.d/apache2 force-reload

then rerun check configuration in browser, yeah, second warning is gone!!!!

to fix the third warning, run:

sudo pecl install apc

and edit php.ini to add 'extension= apc.so', then restart apache2. check the configuration in browser, hola, it's all gone, all the warnings!!!

now can go ahead to have fun with symfony!
