Would it be possible that, if this requirement is not met, it exits
with an informative message instead of just bailing out?

That information message could possibly state something like:

    The same version of perl (5.022) as used by Buildroot is not
    available on your machine.

    You may install a local one by running:
        perlbrew install perl-5.22.2

Note however that my installtion (Ubuntu 16.04) is missing perlbrew; it
is not installed by default.

I am not sure where to go from here. On one side, I thing people dealing
with perl would already have such things installed (or be willing to
install them) on their machine.

On the other hand, we've always tried to keep Buildroot's requirement on
the host as minimal as possible, and perlbrew would be adding yet
another dependency.

I'm undecided. But I'd really like the error message, above! ;-)

Regards,
Yann E. MORIN.
