FWIW, the parameter for lib must be a directory and not a file. Here's what I tried with Exporter-5.67: 
#!/usr/bin/perl -l

BEGIN { 
    unshift @INC, '/root/mylib/lib';
}

use strict;
use warnings;
require Exporter;
use Email::Date::Format;
use lib '/root/mylib/lib';

print "Email::Date::Format: ", $Email::Date::Format::VERSION;
print "Exporter: ", $Exporter::VERSION;
