gscam building failure

edit

Hi all, I am working on fuerte distribution and want to install gscam package

I command :

svn checkout https://brown-ros-pkg.googlecode.com/svn/trunk/distribution/brown_perception

I placed it in my workspace in home /home/salma/ws_salma

But when i rosmake it by

rosmake gscam

it has 1 failure :
