The last step is to make sure that you can reference and include the PHP Client Library files from the directory that you are building your project.
Vale, pues resulta que lo tengo descomprimido tal que así
/var/www/vhosts/dominio.com/httpdocs/librerias/zend/Zend/Loader.php
y en el include path tengo esto
include_path = "/var/www/vhosts/dominio.com/httpdocs/librerias:/var/www/vhosts/dominio.com/httpdocs/librerias/zend"
lo gracioso es que trato de ejecutar el instalation checker y me tira este error
Exception thrown trying to access Zend/Loader.php using 'use_include_path' = true. Make sure you include Zend Framework in your include_path which currently contains: /var/www/vhosts/dominio.com/httpdocs/librerias:/var/www/vhosts/dominio.com/httpdocs/librerias/zend
veis algo de lo que no me esté dando cuenta?
