Zend_View_Stream does not exist
When I did update my trunk version of the incubator this morning, I was getting an error with the message "Zend_View::require_once(Zend/View/Stream.php) [function.Zend-View-require-once]: failed to open stream: No such file or directory".
It seemed that it depends on the 'short_open_tags' php.ini directive, I did turn it off (because I don't use it anyway), but I think that this could be a larger problem for those who are using the short open tags.
This is also a bug currently, because I thought that Zend_View_Stream should emulate short open tags, so it should be enabled when the short_open_tags directive is is turned Off, and not when it is turned On.
