As with all Perl code, there is more than one way to do it.  Another way 
to accomplish what you are trying to do is through the use of 
startup.pl, which is run during apache startup.  (I don't know why that 
error above is occurring so I'm posting this as an alternate approach).

# httpd.conf
PerlPostConfigRequire /home/pennyyh/perl/lib/startup.pl

# startup.pl
use strict;
use warnings;

use Mymodule;
Mymodule->init;

1;

## Mymodule.pm
package Mymodule;

use strict;
use warnings;

our $data;

sub new {
...
}

sub init {
    my $class = shift;
    $data = $class->new;
}

sub data {
    my $class = shift;
    return $data;
}

1;

then in your application you can access $data via $Mymodule::data, or 
better yet access it like so:

my $data = Mymodule->data; # this returns the object created during 

                           # startup

HTH,
