How can I install Zend Optimizer

Has anyone had success with installing Zend Optimizer on their Sheeva plug?

I downloaded the Zend Optimizer v3.3 from http://www.zend.com/en/products/guard/downloads
I am running php 5.2.6 on my Sheeva plug.

After extracting the Zend Optimizer files on the Sheeva plug to the /tmp folder. I removed the included php that was under the zui_files folder, and used a symbolic link to the /usr/bin/php file. I then ran the install-tty command that was included with the Zend Optimizer, and accepted the defaults, except when it asked if I was running Apache, I answered NO. (Although I really am running Apache, I encountered a different problem that would prevent me from installing the Zend Optimizer)

After the install was completed I have the following settings in my /etc/php5/cli/php.ini file:

Code:

[Zend]
zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.3.3
zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.3.3
zend_optimizer.version=3.3.3
zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so
zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_TS.so

However when I run the command

Code:

php -v

Here is the output I receive

Code:

Failed loading /usr/local/Zend/lib/ZendExtensionManager.so: /usr/local/Zend/lib/ZendExtensionManager.so: cannot open shared object file: No such file or directory
PHP 5.2.6-3ubuntu4 with Suhosin-Patch 0.9.6.2 (cli) (built: Mar 31 2009 11:41:43)

I have checked and the file does exist:

Code:

ls -l /usr/local/Zend/lib/ZendExtensionManager.so
-rwxr-xr-x 1 root root 11142 Dec 21 14:09 /usr/local/Zend/lib/ZendExtensionManager.so

Thanks in advance to any advice or assistance that is provided.
