While I can do this for my current project, it's not something that can be done for cards that have on them data that should be retained. And if other data can be replicated only by cloning a card, the position is untenable. I suppose it's my unfamiliarity with Linux. I'm not surprised that there isn't a precompiled version of Perl 5.16 for the Pi, but I was expecting it to be possible to create one. The hours of compiling are guaranteed to put people off using anything but the system Perl on a Pi, which may be why Python is their language of choice.
