Markdown is definitely not running under Perl 5.6 or higher, given
the above errors.

That's not going to work when Markdown is running as a Movable Type
plug-in. The shebang line (#!/usr/bin/perl) only has an effect when
you're running Markdown as a standalone Perl script.

Within MT, Markdown runs in the same process as the Movable Type CGI
app, and it looks like on Arthur's server, that's Perl 5.005.

Perl 5.6.0 shipped *4 years ago*; while it's unfortunate that many
systems are still running older versions, there's no way Markdown
will ever run on anything older than 5.6.

I agree, this is a fine use of the list. The basic idea is that
anything Markdown-related can be posted. However, once a thread
diverges from discussion of Markdown itself, it ought to be taken
off-list.
