non c'est normal, install APC, le module XSL et tu mets le short tag et le gpc sur Off

Bonjour,
je voudrais utiliser un framework en php (Symfony) :
Mais quand je regarde ma config j'ai des warning ?
Au préalable il ma dit que je n'avais pas installé php, alors que j'avais utiliser tasquel (je suis sous linux)
sudo tasksel install lamp-server
pour installer lamp
http://doc.ubuntu-fr.org/lamp
J'ai donc installé php 5 une seconde fois pour ensuite lancer le fichier de configuration et constater pas mal de warning.

[[WARNING]] XSL module is installed: FAILED
[[WARNING]] A PHP accelerator is installed: FAILED
*** Install a PHP accelerator like APC (highly recommended) ***
[[WARNING]] php.ini has short_open_tag set to off: FAILED
*** Set it to off in php.ini ***
[[WARNING]] php.ini has magic_quotes_gpc set to off: FAILED
*** Set it to off in php.ini ***
Sa me semble beaucoups, est-ce habituel dans symfony ?
Merci
