I have a perl script that runs fine on Windows 10. But I am having a tough time getting it to run on the Mac High Sierra OS X platform. I installed all the different flavors of Perl, perl brew, etc and Xcode, Xcode tools, cpan, etc . . . But the script always stalls out because some dependency is not available.

The latest error says, " LWP will support https URLs if the LWP::Protocol::https module is installed.

So, in Terminal I enter, "sudo cpan LWP::Protocol::https", and get back a zillion lines of messages that I can neither makes heads or tails of. Partially reproduced below:

In Windows, the Perl script just runs fine. In Mac -- no way. I don't understand why it so difficult for Perl to run in the Mac OS X environment? Is it a permissions issue? Is it a path problem? I just don't know and feel so lost :(
