HTML::Tree (Error: Not installed. for CompareRevisionsAddOn)

I am trying to install and configure FOSWIKI on a Godaddy Linux web hosting.

When I run the configure.pl from the browser, I get below error:

Web Server Environment

HTML::Tree	Error: Not installed. for CompareRevisionsAddOn

=============================================

My Perl version is:

Perl version	5.008008 (linux) Note that by convention "Perl version 5.008" is referred to as "Perl version 5.8" and "Perl 5.008004" as "Perl 5.8.4" (i.e. ignore the leading zeros after the .)

MY @INC library path:

@INC library path

/home/content/43/8247343/html/foswiki/lib/CPAN/lib/arch /home/content/43/8247343/html/foswiki/lib/CPAN/lib/5.8.8/i386-linux-thread-multi /home/content/43/8247343/html/foswiki/lib/CPAN/lib/5.8.8 /home/content/43/8247343/html/foswiki/lib/CPAN/lib /home/content/43/8247343/html/foswiki/lib /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.8.8/i386-linux-thread-multi /usr/lib/perl5/5.8.8 This is the Perl library path, used to load Foswiki modules, third-party modules used by some plugins, and Perl built-in modules.

I don't know the mechanism for adding CPAN modules on Godaddy. You will need to install HTML::Tree or you can disable the CompareRevisionsAddonPlugin. I believe that this will default Foswiki to use the old rdiff function for comparing topics. A bit of google searching suggested that officially you would need to use their virtual hosting service to install CPAN, but another reply suggested copying the HTML::Tree modules into a local CPAN directory.
