Piwik v 2.8 and PHP 5.3.3 (no replies)

Hi,

I just download Piwik 2.8.0
The first page "ticked" everything ( roughly) OK, except that It says :

1) " Version PHP > 5.3.3 (I am running 5.3.3-37 if I remember correctly ) " AND it says : "Erreur: Version PHP > 5.3.3 requis"
So, I am bit confused !!


2) Optionnal :
GD > 2.x + Freetype (graphiques) AND GD > 2.x + Freetype (graphiques)
Les sparklines won't work => Why ? What should I do ?

Thanks for your help
