IIIF Toolkit installation problem

Hello,

I cannot install the IIIF Toolkit plugin due to the following error:

The configured PHP path (/usr/local/bin) does not point to a PHP-CLI binary.

RuntimeException: The configured PHP path (/usr/local/bin) does not point to a PHP-CLI binary. in /home/corpus/public_html/omeka_classic/application/libraries/Omeka/Job/Process/Dispatcher.php:124

However, the PHP-CLI is located in this directory. Anyone has an idea where does this issue come from ?

Thank you very much for your help!
