Unable to compile as per instructions

[CSBaum]

After following the README.md instructions for building the raspi_interface, i am getting the following error from rosmake:

pi@raspberrypi ~/raspi_interface $ rosmake
[ rosmake ] rosmake starting...
[ rosmake ] No package or stack specified. And current directory 'raspi_interface' is not a package name or stack name.
[ rosmake ] Packages requested are: []
[ rosmake ] Logging to directory /home/pi/.ros/rosmake/rosmake_output-20140917-153300
[ rosmake ] Expanded args [] to:
[]
[ rosmake ] ERROR: No arguments could be parsed into valid package or stack names.

I have tried both the master and catkin without success.

Bumped, same problem.

Experienced the same problem as above- executing
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:pwd``
from within the raspi_interface and bosch_driver directories seems to work. It adds these to the ROS package path (So they know where to look for them).
