Like a number of other monks, I don't understand why you don't use version 5.24 of Perl and the necessary TLS interface module and solve the problem without involving Perl 5.6 at all. It would be helpful if you could explain this point. Is it perhaps the case that Perl 5.6 is the system Perl on the server in question and you are unsure about how to install and run a later Perl version?

If you avoid the work-around and just do the work, you may find that you have a lot less work to do. See XY Problem.
