To run Piwik you need at least PHP version $piwik_minimumPHPVersion

Unfortunately it seems your webserver is using PHP version $piwik_currentPHPVersion.

Please try to update your PHP version, Piwik is really worth it! Nowadays most web hosts support PHP $piwik_minimumPHPVersion.

Also see the FAQ: My Web host supports PHP4 by default. How can I enable PHP5?
