You mention that the code needs work. Here are some things I see that can be improved.
 

The prototypes on all of your subroutines conflict with the code in the subroutines. For example: sub new ($){ says that new takes a single argument, but then two arguments are shifted from @_: 

        my $self = shift;

        $self = bless {};

        $self{'index_path'} = shift;

It is fortunate in this case that current versions of Perl ignore prototypes on method calls. :)
 

Your hardcoded LOCK constants are not platform compatible: 

        $LOCK_SH = '1';
        $LOCK_EX = '2';
        $LOCK_NB = '3';
        $LOCK_UN = '4';

The constants from Fcntl should be used instead.
 

Globs, which are entries in the symbol table, do not include lexical variables, which are held outside the symbol table. In this code: 

        my %deleted_pair = ();

        $deleted_pair{$key} = $TABLE{$key};

        delete ($TABLE{$key});

        $self->update_index_table(\%TABLE);

        return (*deleted_pair)

the glob that is returned does not include the lexical hash that was just made. You probably want to return the hash itself, or a reference to it.
 

These are a few of the more egregious issues with the current state of your module. I hope you will continue making improvements.
