Advanced Website Help?

[kpic]

Not sure if anyone here can help with this but as this is the only forums I come to daily and a search of support forums for website issues seems sparse, so maybe I can get some help from someone here smarter than me with this.

I have a website with a few different components to it (main page, web-store etc.)

Several of those pages come up as "Software Error", for example if the page is id as

h**p://www.mysite.com/cgi-bin/dc/manage.cgi

Every .cgi page in this cgi-bin/dc folder comes up as this software error.

My hosting provider has not been too helpful as they just keep saying it's a site provider issue.

The site provider responded with;

This error indicates the Perl module Date::Calc is not installed.

Please contact your hosting provider and ask them to ensure the following Perl modules are installed:
Date::Calc, MIME::Lite, MIME::Types, Crypt::CBC, Crypt::Blowfish, PHP::Serilization and XML::Simple

The Perl module installation is the responsibility of your hosting provider. If your hosting account uses the cPanel control panel software you should be able to install the Perl modules yourself, if you do not use cPanel then B___Host (I edited out my host provider) will be responsible for the Perl module installation as you will not have access to do this yourself.

I know some basics but all of that sounds like Chinese to me. I do have access to my cPanel but unless I am doing this wrong I searched in my cPanel\Perl Modules and cannot find one of these Perl modules mentioned?

I do have a FTP backup of the site but I only backed up my PUBLIC_HTML folders and nothing else, I am guessing the Perl modules are in my \Home folder?

So what do the smart people of CP say, any ideas of what this means?

And mods if 19now11 responds in this thread at any point please just kill it.
