[PATCH] x-to-1: Honor $PERL

From: Alexandre Duret-Lutz
Subject: [PATCH] x-to-1: Honor $PERL
Date: Wed, 12 Dec 2012 11:05:45 +0100

* build-aux/x-to-1.in: Run $HELP2MAN via $PERL so that the user gets a
chance to use his preferred version of Perl.  This is typically
required by Darwin users whose default /usr/bin/perl do not have all
the libraries required by help2man, and who need to use their MacPorts
installation of Perl instead.
