I am trying to port some perl code over from my OS X 10.6.8 server to my new OS X 10.12.6 server. When I run the code, it trips over a missing WWW::Curl::Easy module:
------------------------------ 
[ns3:~/linkrabbit] administrator% ./linkrabbit.pl -s iq
Can't locate WWW/Curl/Easy.pm in @INC (you may need to install the WWW
+::Curl::Easy module) (@INC contains: /Users/administrator/perl5/perlb

------------------------------
Sure enough, WWW::Curl::Easy is not installed. So I pop over to cpanp to install the module, but fail miserably:

[ns3:~/linkrabbit] administrator% sudo cpanp -i WWW::Curl::Easy

I have googled my brains out (and I google for a living), but haven't been able to get past this point for months. At this point, I'm quite lost. I'm hoping that I can reach out to someone who might better understand my predicament.

Can anyone assist?

My humble thanks.
