First make sure that you have all the prerequisite Perl modules. You can install them easily, using CPAN.
The following CPAN usage example has all the needed modules on one line.
perl -MCPAN -e shell install Data::Dumper Digest::base Digest::SHA1 LWP::UserAgent Crypt::SSLeay XML::Simple XML::DOM Error Cache::FileCache Class::MethodMaker Bundle::DBD::CSV DBI DBD::CSV Archive::Zip Config::IniFiles install Business::Shipping
Note: The following comes with perl 5.8.2
POSIX Fcntl File::Find File::Copy
perl Makefile.PL && make && make test && make install
Or, expressed on separate lines:
perl Makefile.PL make make test make install
