-# For now, let's assume that most Linux users get their /usr/bin/perl
-# from some packaging system, so that those compiling from source are
-# probably the more experimental folks and hence probably aren't
-# intending to replace /usr/bin/perl (at least just yet).
-# This change makes linux consistent with most other unix platforms
