Missing resource orocos_bfl

Hi
I would like to install and run "extendedKalmanFilterComponentRobot"
in ROS. I have installed orocos_toolchain (omniorb failed). When I try to
install the dependencies for "youbot_supervisor" it is giving the following
message "Missing resource orocos_bfl". I followed the directions in your
website and installed bfl (the folder I have is bfl not orocos_bfl). I am
still getting the same message. Would you please let me know how I can
install orocos_bfl on my machine? (I am using Ubuntu 10.04 LTS- the Lucid
Lynx).
I am new to unix, so could you please be more specific in your answer.

Thank you
Solmaz
