OK, here you go. A few adjustments: ConfigThisJunk.pm is actually ExportScalar.pm and the script name is ImportTest.pl. The package is in the folder 'D:/Marcos/Perl/MSB/SS' in my Windows machine. Hence, your line got modified to:

 perl -wle"use lib 'D:/Marcos/Perl/MSB'; use SS::ExportScalar; print $INC{'SS/ExportScalar.pm'};"

and that resulted in

D:/Marcos/Perl/MSB/SS/ExportScalar.pm

And then the results of the type statements:

type ExportScalar.pm
use strict;
use warnings;
use Exporter;
our @ISA = qw( Exporter );
our @EXPORT_OK = qw( DEBUG );

our $DEBUG = 1;

sub DEBUG {
   if (@_) { $DEBUG = shift; }
   return $DEBUG;
}
1;

type ImportTest.pl
#!/usr/bin/perl -w
use strict;
use warnings;
use lib 'D:/Marcos/Perl/MSB';
use SS::ExportScalar qw( DEBUG );
my $x = 123;
print("debug: x is $x\n") if DEBUG;

Now I execute it:

perl ImportTest.pl
Bareword "DEBUG" not allowed while "strict subs" in use at ImportTest.
+pl line 7.
Execution of ImportTest.pl aborted due to compilation errors.

Now, I change the strict statement in ImportTest.pl:

type ImportTest.pl
#!/usr/bin/perl -w
use strict qw (vars refs);
use warnings;
use lib 'D:/Marcos/Perl/MSB';
use SS::ExportScalar qw( DEBUG );
my $x = 123;
print("debug: x is $x\n") if DEBUG;

[download]
perl ImportTest.pl
Bareword found in conditional at ImportTest.pl line 7.
debug: x is 123
