Instead of a random directory structure, I prefer to create a proper module:

h2xs -AXc -n FooBar

...which will create a FooBar directory that contains the following:

Changes
MANIFEST
Makefile.PL
README
lib-
   |-- Foobar.pm
t/
[download]

Then, create a FooBar directory within the lib dir, and put your Bar.pm and Foo.pm in that. I use the FooBar.pm as a module that contains any methods that will be common to more than a single sub class. So, in Foo.pm and Bar.pm, I'd have:

use base qw( FooBar );
[download]

In FooBar, some of the common subs I'd have are a generic new(), database setup subs, configuration file setup subs etc. Then, unless Foo or Bar require specific, non-generic versions of these subs, they will automatically be inherited when use()ing FooBar::Bar and FooBar::Foo without having to recreate the subs in each module file.

All in all, with the directory structure above and with this setup you could have:

# lib/FooBar.pm

package FooBar;

sub new { 

    my $class = shift;
    my $args  = shift;

    my $self = bless { 
                name => $args->{ name },
                age  => $args->{ age },
              }, $class; }

    return $self;
}

# lib/FooBar/Foo.pm

package FooBar::Foo;

use base qw( FooBar );

# no new() sub, it's inhereted

sub age {

    my $self = shift;
    my $args = shift;

    $self->{ age } = $args->{ age } if $args->{ age };

    return $self->{ age };
}

# lib/FooBar/Bar.pm

package FooBar::Bar;

use base qw( FooBar );

# no new again

sub name {
    
    my $self = shift;
    my $args = shift;

    $self->{ name } = $args->{ name } if $args->{ name };
 
    return $self->{ name };
}

# foo.pl

use FooBar::Foo;
use FooBar::Bar;

# don't need to 'use' FooBar here

my $foo = FooBar::Foo->new({
                       name => 'stevieb',
                       age  => '35',
                  };

my $current_age = $foo->age();

my $year_older  = $foo->age({ age => 36, });

Because you have a proper module setup, simply:

perl Makefile.PL
sudo make install
[download]

to begin using your modules system-wide

I hope this helps in some way
