=head1 NAME
BSDPAN::ExtUtils::MM_Unix - Override ExtUtils::MM_Unix functionality
=head1 SYNOPSIS
None
=head1 DESCRIPTION
BSDPAN::ExtUtils::MM_Unix overrides two subs from the standard perl
module ExtUtils::MM_Unix.
The overridden init_main() first calls the original init_main(). Then,
if the Perl port build is detected, and the PREFIX stored in the
ExtUtils::MM_Unix object is not F</usr/local/>, it proceeds to change
various installation paths ExtUtils::MM_Unix maintains, to match PREFIX.
The overridden tool_xsubpp() sub temporarily undoes the change in the
environment done by the overridden init_main(), so that xsubpp(1) and
other XS tools will be searched in the right place.
Thus, BSDPAN::ExtUtils::MM_Unix is responsible for making p5- ports
PREFIX-clean.
