install_driver (mysql) failed: unable to locate DBD / mysql.pm

I have tried to install a Perl / CGI script that uses a MYSQL database.
I had the error

install_driver (mysql) failed: unable to locate DBD / mysql.pm …

I'm using Cloudlinux and Cpanel.
I've tried to install DBD :: Mysql in cpanel and WHM but I still get the same error.

What should I do?
I normally use PHP scripts.
