Suse 9.3 session function needed

I am running Suse 9.3 with apache 2.
When following the setup guide and placing the gallery folder in /srv/www/htdocs I could not finish setup because of a php function error related to session_id() .

After some googling I found out Suse needs the php4-session module or php5-session in case you are using that.

I could find anybody else with this problem, just posting in case this can help somebody.
cheers!
