Hello first timer here posting~ Trying to get a better grip on perl module and,I was testing out below script, When I use "use Acme statement", it loads the module properly and it works. However, when I want to test out the ' use lib ' it comes up with below error message(looks like it is able to locate but cannot read or import back the function for whatever reason??). 
[root@myserver perl]# ./logtest2.module.pl
Undefined subroutine &main:pen_log called at ./logtest2.module.pl line
+ 23.

Code: 
#!/usr/bin/perl -w

use strict;

#
# Below use Acme works ; just uncomment it
#

#use Acme::Webserver::Logger;


#
#  See if you can understand and do use lib 
#

use lib '/usr/lib/perl5/site_perl/5.8.8/Acme/Webserver';
require Logger;
#require 'Logger.pl';

#use Logger;
# /usr/lib/perl5/5.8.5/Acme/Webserver

open_log("webserver.log");


write_log(1, "A basic message");

write_log(10, "A debugging message");

log_level(10);
write_log(10, "Another debugging message");

close_log();
