Libs not loading when in folder

[eluser]Vang[/eluser]
I try to load a library from a controler using $this->load->library('libs/libraryname');
I get "Unable to load the requested class: authorization"
When i move the file in the libraries folder instead of libraries/libs it loads fine.

My installation:
CI 1.7.0
Apache 2.2.9
php 5.2.6
on ubuntu 8.10
