Zend_Tool: Fatal error: Cannot redeclare class Zend_Loader

I am able to create new projects with...

zf create project ProjectName

...but this creates a project without copying the Zend Framework library. So I copy ZF into my project library and try to create a controller...

zf create controller auth

...and I get this message:

Fatal error: Cannot redeclare class Zend_Loader in /home/andrew/Projects/test/library/Zend/Loader.php on line 31

What is wrong with my setup? How can I get Zend_Tool to work like it's supposed to work?

In your config file (application.ini) comment out this line with a semicolon:

;includePaths.library = APPLICATION_PATH "/../library"

This will prevent Zend_Loader from being included twice.
