Zend_Loader_Autoloader actually understands a concept of versioned ZF
libraries already, which would make (2) an obvious choice. On the
following page:
http://framework.zend.com/manual/en/zend.loader.autoloader.html
look for the section entitled "Selecting a Zend Framework version".
Basically, have the latest version of ZF symlinked to a standard
directory, use the Zend_Loader_Autoloader class from that directory,
and then point it to the base directory and indicate a version you wish
to use.
Zend_Application is also aware of this information, and you can
configure it with the keys "autoloaderzfpath" and "autoloaderzfversion".
This approach allows you to have parallel ZF installs, while still
re-using them if several applications share the same versions.
Additionally, you can keep only the latest version of a given minor
release at a time -- these introduce BC breaks *extremely* *rarely* (as
in: only for security issues), which allows you to further minimize the
number of versions you retain on your system.
