I have a simple module based on tachyon's tutorial: 
#!/usr/bin/perl -w

# module path: c:/Perl/myperl/CWI/Message.pm

package CWI::Message;

use strict;
use Exporter;
use vars qw( $VERSION @ISA @EXPORT );

$VERSION     = 1.00;
@ISA         = qw( Exporter );
@EXPORT      = ( &get_msg );

sub get_msg{
  return "message from module\n";
}

1;

This script will only work with a full package name (see the comments): 
#!/usr/bin/perl -w

# script path: c:/Perl/myperl/dev/test_mod.cgi
# module path: c:/Perl/myperl/CWI/Message.pm

use strict;
use lib 'c:/Perl/myperl';
use CWI::Message;

# next print statement produces:
# 'Name "main::get_msg" used only once'
# print get_msg;

# prints ok
print CWI::Message::get_msg;
