I looked at %INC after the program got started and dumped versions. Here's what I got. The code:

#!/usr/bin/perl
use strict;
use diagnostics;
use lib ".";
use MyTable;

print <<"END";
Exporter = $Exporter::VERSION
Carp = $Carp::VERSION
XSLoader = $XSLoader::VERSION
Class::DBI::Query = $Class::DBI::Query::VERSION
DynaLoader = $DynaLoader::VERSION
lib = $lib::VERSION
Class::Trigger = $Class::Trigger::VERSION
Exporter::Heavy = $Exporter::Heavy::VERSION
DBI = $DBI::VERSION
Class::WhiteHole = $Class::WhiteHole::VERSION
MyDatabase = $MyDatabase::VERSION
constant = $constant::VERSION
Class::DBI::ColumnGrouper = $Class::DBI::ColumnGrouper::VERSION
strict = $strict::VERSION
diagnostics = $diagnostics::VERSION
base = $base::VERSION
vars = $vars::VERSION
Config = $Config::VERSION
warnings::register = $warnings::register::VERSION
warnings = $warnings::VERSION
Class::Data::Inheritable = $Class::Data::Inheritable::VERSION
Ima::DBI = $Ima::DBI::VERSION
Class::Accessor = $Class::Accessor::VERSION
MyTable = $MyTable::VERSION
Class::DBI = $Class::DBI::VERSION
overload = $overload::VERSION
AutoLoader = $AutoLoader::VERSION
Data::Dumper = $Data::Dumper::VERSION
END

The output:
