I think 'say' is Perl 6?

It's also available in perl 5 if you request it:

C:\>perl -e "say 'ok';"
String found where operator expected at -e line 1, near "say 'ok'"
        (Do you need to predeclare say?)
syntax error at -e line 1, near "say 'ok'"
Execution of -e aborted due to compilation errors.

C:\>perl -Mfeature="say" -e "say 'ok';"
ok

C:\>perl -E "say 'ok';"
ok

C:\
[download]

And Strawberry Perl's a pain when someone who's NOT a Perl Monk has to figure out how to use a module that you've downloaded from CPAN

That's something that most of us had to go through - and it gets easier with practice and experience.

is there a relatively easy way a NON-Perl Monk can upgrade the Perl that DWIM Perl and Padre are using to Perl 6?

No, perl 6 is quite different to perl 5. You can run perl 5 code/modules on perl 6 (using Inline::Perl5) - if that's what you are seeking.
Last time I tried Inline::Perl5, it was quite good on Linux, but pretty crap on Windows.
