I'm a Perl user, but I generally refuse to read Perl code which
doesn't utilize 'use warnings/-w' and 'use strict'.  There are just too
many crazy bugs and 1980s constructs which go unnoticed without them.

Not related to your question, except that you'll have to deal with
this in Python too:

I really suggest letting the user's $PATH decide which dig to call.
/usr/bin is always in the path.  /usr/sbin may not be, but if that's a
problem for your users, just let your script start by appending it to
the pre-existing $PATH.  You don't even have to do OS detection on
that one -- it's safe to do everywhere.
