Error when using Oreon to complete the install

[rbizzell]

I receive this error message when I am using Oreon to complete the installation of nagios through my web browser. Critcal:mysql.so not loaded in php.ini Critical: gd.so not loaded in php.ini
I am new at this. What do I need to do to fix these two error messages. I appreciate all your help

you must install a lot of dependency before install Oreon.

In your case for the moment : php-gd and php-mysql
