         # behavior, change the output location.

Nit: You can remove this line once JSON.pm is landed, right? Let's land JSON.pm
first.

Actually, this line is only useful *after* JSON.pm lands.

This include line is necessary because otherwise Perl on Mac doesn't know where
to find the library (we don't have a standard third-party Perl module location).
Agreed -- otherwise we can't even test that it works on Mac!
