Where to enable session handling?

[strange1]

phpinfo says this:

Configure Command  './configure' '--prefix=/usr' '--datadir=/usr/share/php' '--disable-session' '--without-mysql' '--disable-cli' '--without-pear' '--with-apxs2=/usr/sbin/apxs2-prefork' 'i586-suse-linux'  

How can I enable sessions? I know that I need to recompile php but how do I do that via ssh?

Apache2 running on SUSE 9.1

Thanks in advance

From the manual:

"Installation
Session support is enabled in PHP by default. If you would not like to build your PHP with session support, you should specify the --disable-session option to configure."

it is currently disabled, I want to enable it
