See the various resources at (Note: I
created Perl-Begin and maintain it).

Perhaps try this search - .

Yes, you do, unless the Perl extension is statically linked to it. I have no
idea about how to install OpenSSL on Windows (You can try searching the web).

As you've seen - it did. I should further note that for Windows, most
clueful people would recommend using , which is
free-as-in-speech, open source, community maintained (and naturally -
gratis), and better, over ActivePerl, which is proprietary, or , which contains Strawberry Perl and other
extensions (although it seems that now DWIM Perl is stuck at perl-5.14.x, which
was end-of-lifed).

Finally, I should note that there's already perl-5.18.1, so you should use it
instead of perl-5.16.x.
