ActionView::Template::Error (Permission denied - /.phantomjs) in production environment

[lphm]

Hello,
I have an error when pushing my rails application in production environment (CentOS 6 - Apache) :

ActionView::Template::Error (Permission denied - /.phantomjs)

But phantomjs is installed on my server. And when I test with rails c command (always in production environment), screencap found phantomjs correctly.

Where can I put real path of phantomjs in my Rails application configuration, in production mode ?

Thanks for your help.
