Hello PAR-Packers,

as suggested by Roderich on ***@perl.org, I am submitting this
observation as a bug report.

The symptom: My application adds a local directory to @INC with 'use
lib'. After packing with pp, modules in this directory are no longer
found. Surprisingly, when I add more than one library, only the last
'use lib' fails. So, I do have an (ugly) workaround, but no idea about
whether it has side effects.

Versions: Perl v5.18.2, PAR::Packer 1.017,
Linux ubuntu 3.13.0-45-generic

Here's a simple demo: 'foo' is added to @INC as intended, 'bar' isn't.
----------------------------------------------------------------------
$ cat local_includes.pl
use Data::Dumper;
use lib 'foo';
use lib 'bar';
print Dumper(\@INC);
$ pp local_includes.pl
$ ./a.out
$VAR1 = [
'foo',
sub { "DUMMY" },
'/tmp/par-68616a/cache-5bde0b3f6eab9c5f0be91ed26371a4bb8b7cbac1/inc/lib',
'/tmp/par-68616a/cache-5bde0b3f6eab9c5f0be91ed26371a4bb8b7cbac1/inc',
sub { "DUMMY" },
sub { "DUMMY" }
];
----------------------------------------------------------------------

PAR::Packer are really awesome if you want to run Perl applications on
Windows tablets with 32GB SSDs, where the 500MB of Strawberry begin to
hurt badly...

$ cat local_includes.pl
use Data::Dumper;
use lib 'foo';
use lib 'bar';
$ pp local_includes.pl
$ ./a.out
$VAR1 = [
'foo',
sub { "DUMMY" },

The bug is actually in PAR (not PAR::Packer), fixed in PAR 1.009, just uploaded to CPAN.

Cheers, Roderich
