Btnx cannot install...?

[Skywatch]

Hi,

I wanted to try btnx to add all the mouse buttons to my Xbian installs. Only trouble is it won't install.... I get....

Terminal

xbian@cinema2film ~ $ sudo apt-get install btnx
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package btnx

I guess it is something to do with the repo config?

Any ideas out there? - Anyone got this installed and working?
