Unable to load library in HMVC of wiredesign

[eluser]ankur0101[/eluser]
Hello,
I have latest CI with HMVC of Wiredesign.

I have a module called accounts.
Structure is like this >

modules
--accounts
--controllers
--models
--library
--status_message.php


I want to call status_message library in model. Hence I wrote

Code:

$this->load->library('accounts/status_message');

But CI showing error as Unable to load library status_message.
Very strange problem.
