As others have said, fork the module at a point free of the problems you mention. Then closely examine the current version for anything you can high grade(mining expression for take the good stuff). If you find something worth while, incorporate it into the fork. Document everything and then place in back on CPAN. Given the number of seemingly cloned offerings, I would guess this has happened before.As a fairly weak plan B, contact the original author and see what remedy might follow if any.
