To demonstrate the other/related problem, involving XS modules, create 
sha.pl as:
#!/usr/bin/perl
use strict;
use warnings;
use Digest::SHA1;
my $digest = Digest::SHA1->new;


Create a PAR with:
pp -p -o sha.par sha.pl
(Do this on a machine with version 2.12 of Digest::SHA1, eg. from CPAN)

Then copy to new machine (which contains 2.11 of Digest::SHA1, eg. from 
Debian repository), and run it:

to...@arya-tmp$ perl -MPAR sha.par
Digest::SHA1 object version 2.11 does not match bootstrap parameter 2.12
