Well, IMO, blacklisting just doesn't fix the problem here if the problem is
/long/long/long/path/to/perl. Because whether from packaged staging or from
really built perl-native the perl will be there anyway and so is the chance of
breakage.
Maybe some automatic
$ sed -ri "s,#!.\s*${STAGING_NATIVE_BINDIR}/perl,#!/usr/bin/env perl,"
somewhere (and probably something more hacky to only catch the first line)?
