rosdep doesn't recognize OS

edit

Hi, I'm trying to install ROS fuerte on my raspberry pi running raspian (debian based). Everything is running fairly smooth, however rosdep doesn't seem to recognize my OS, even though I've set it using ROS_OS_OVERRIDE.

Executing: python -m rospkg.os_detect results in:

OS Name:     debian
OS Version:  squeeze
OS Codename:

But executing: rosdep install -a results in:

Executing script below with cwd=/tmp
{{{
#!/bin/bash
export PREFIX=/usr/
[ f932cebad87302d8ea0ec1fd39b24d99 = `cat $PREFIX/include/eigen3/eigen-version.installed` ]

}}}

cat: /usr//include/eigen3/eigen-version.installed: No such file or directory

else
  false
fi

}}}

Since the version brackets are empty, I'm guessing that rosdep doesn't acurately recognizes the OS Override. Is there another flag I can set?
