can not install gallery

i am stuck here :
We're having trouble creating a place for your photos. Can you help? We need you to create a directory called var in your gallery3 directory. This sample code works for most users. Run it in the gallery3 directory

i made a var directory and made it writable, but it keep saying the same thing. i made a phpinfo.php file and attach it here. i dont have any clue why is this happening.
i am open to new ideeas
