Importing Dependency Version

perldc has asked for the wisdom of the Perl Monks concerning the following question:

I'm using Email::Date::Format version 1/004 which has a dependency on Exporter 5.57. My server only has an older Exporter 5.562. I downloaded the latest version of Exporter which is currently 5.58 and I put it in my lib directory for my current project. Is there a way that I can tell the Email::Date::Format module to use the version of Exporter in my lib folder? In my main script i'm currently using

use lib qw{./lib/Exporter};
use Exporter 5.68;
[download]

I've even tried editing Format.pm and changing

use Exporter 5.57 'import';
to
use lib qw{./lib/Exporter};
use Exporter 5.68 'import'; #thinking maybe if i specific the exact ve
+rsion it may find it

Is there a way that I can tell the Email::Date::Format module to use the version of Exporter in my lib folder? Yes, by telling perl from your script `use lib '/absolute/path/to/my/lib'; use Email::Date::Format;` [download] I've event tried editing Format.pm and changing In that case try replacing `use Exporter 5.57 'import';` only with `use Exporter ;` and nothing else `use lib...;` only belongs in scripts OTOH, 5.6.1, the perl you seem to have, is 12 decades old (120 years), you can install a newer perl like citrusperl in your home directory, or use perlbrew or perlall to do the same from sources	[reply] [d/l] [select]

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;` [download]	[reply] [d/l]

That script seems to work and use the Exporter in my projects lib directory. I'm not sure why but I was using: `use strict; use warnings; use lib qw{./lib}; print "Email::Date::Format: ", $Email::Date::Format::VERSION; print "Exporter: ", $Exporter::VERSION;` [download] which did not work. Simply moving the use warnings; to the end does work. `use strict; use lib qw{./lib}; use warnings; print "Email::Date::Format: ", $Email::Date::Format::VERSION; print "Exporter: ", $Exporter::VERSION;` [download] Apparently there is a special order to for "use" which I did not know about.
