Hello,
I am not quite sure regarding this matter...
I don't have installed 0.7.0, my old sites are still under 0.6.0 (and i won't switch now cause i am afraid of potential compatibility problems) but using 0.6.0 i would simply put Zend.php into your localhost, and also Zend folder....
I think (but not sure), your problem has to do with:
Using Zend_Controller in subfolder
