Script cannot find perl Data:Dumper module

Question

Good day. I live in Australia and use a script called Shepherd to update my mythtv program listings.
After upgrading a couple of days ago (first time in about 6 months) Shepherd has stopped working.
Shepherd doesn't seem to find the perl data-dumper module, which is part of the base perl install.
All my packages are up to date as of this post, and I am on the current kernel -
uname -r
3.4.9-1-ARCH
~/.shepherd/shepherd --check
ERROR:
Mandatory module 'Data::Dumper' not found.
Please see the Wiki at <a href='http://svn.whuffy.com/wiki/Installation' class='bbc_url' title='External link' rel='nofollow external'>http://svn.whuffy.co...ki/Installation</a>
for details on how to install this module.
Shepherd is updating ~/.shepherd/output.xmltv (the listings information scraped from the net) but evidently needs the dumper module to post the data into MythTV.
I'm not sure if it has something to do with this, which I don't properly understand -
The current Arch Linux default perl installation installs updates to core modules into the perl core directories, creating file conflicts.  Examples include modules such as Data::Dumper and version.
which is mentioned here.
I appear to have it installed as part of the perl base package -
sudo pacman -Qi perl
Name : perl
Version : 5.16.1-1

perl-cpan-meta-yaml=0.007 perl-cpanplus=0.9121 perl-cpanplus-dist-build=0.62 perl-data-dumper=2.135
So it seems Shepherd is suddenly not finding it for some reason, after the upgrade.
I tried installing the perl-data-dumper packages from the AUR (simple and concise) and neither of those made any difference.
I also tried installing the module with a cpan command (as root) but that gave me errors (which I'd rather not have to deal with unless I have to to fix this issue).

It says that the 02packages.details.txt.gz file is missing, but it looks like it's there -

I thought I might uninstall and reinstall perl but I got dependency errors and I'm not game to force an uninstall unless I get advice to do so -

Results as follows -
perl -MData::Dumper -e1
Perl API version v5.14.0 of Data::Dumper does not match v5.16.0 at /usr/lib/perl5/site_perl/XSLoader.pm line 95.

I ran the full delete command after backing up the directories (there was a lot in them)
rm -rf /usr/lib/perl5/site_perl/* /usr/share/perl5/site_perl/*
This resulted in a different missing module -
$ sudo rm -rf /usr/lib/perl5/site_perl/* /usr/share/perl5/site_perl/*
$ ~/.shepherd/shepherd --check
ERROR:
Mandatory module 'List::Compare' not found.
I restored the backup and deleted only Data::Dumper but then got a missing XMLTV module -
$ ~/.shepherd/shepherd --check

Following this post, I did the following, which returned no results -
https://bbs.archlinux.org/viewtopic.php?pid=1110598
$ sudo pacman -Qml | awk '/_perl\/auto\/.+\.so$/ { print $1 }' | uniq
I then did the following -
$ sudo rm -rf /usr/lib/perl5/*
$ sudo pacman -S perl

Oops. Then saw your next post saying not to do that as you'd lose the vendor modules, which I did. I had backed up so I restored, so still have the vendor stuff.
In case its of any assistance, this is what my perl lib and share directories look like -
