I need for a Help to install OCS on CentOS

Hey guys hows going ?!

I'm trying to install on CentOS but I have had a problem with this

Checking for Apache2::SOAP PERL module...
*** Warning: PERL module Apache2::SOAP is not installed !
This module is only required by OCS Inventory NG SOAP Web Service.
Do you wish to continue ([y]/n] ?y
Checking for XML::Entities PERL module...
Found that PERL module XML::Entities is available.

Have you had the same problem, please try to help me!

Best wishes
