Introduce an OPTION to decide whether to make the module active. Disable
it by default.
This module is a 207-line script that checks what version of perl you're
using, and then makes some bird-themed comments about it. If you're running
the current stable version of perl, it tells you that you should downgrade
to an old version, or use a personal fork from "schmorp". FreeBSD does not
support that fork. Other features of this module include requiring keyboard
input. Previous versions featured dropping build output in favour of colour
sequences. The module provides no other feature than those listed above.
At best, the comments are inaccurate for FreeBSD. At worst, they can block
input or cause end-users to install personal forks that we do not support.
FreeBSD ports does a much more comprehensive job of checking perl versions
already. If this module is updated to perform some sort of functionality in
the future, the ACTIVATE option can be easily enabled or removed.
