Sorry, this is not an answer, but I stuck at the same procedure. My problem occurs, when I try to compile the first message folder (roscd ipc_roslib && make). The output message is:
[ rosmake ] rosmake starting...
[ rosmake ] Packages requested are: ['ipc_bridge_ros']
[ rosmake ] Logging to directory <my_dir>/.ros/rosmake/rosmake_output-20121108-150035

I guess, that the folder ipc_msgs is not at the right place (I did not see an intruction for that, thus I placed it into the ipc_bridge_stack folder, which is agained placed into the ROS package/stack folder).
EDIT:
When compiling the message folder, an error similar to "unknown command "mex"" could appear. This happens, when the matlab command "mex" is not available in the environment variable "PATH". To do so, use the following line in your .bashrc script:
export PATH=<your path="" to="" matlab="">/bin:$PATH
With it, you should be able to call the mex command from anywhere in the shell.
It worked for me with Electric, but now I have the same problem with Fuerte and Ubuntu 12.04. Any suggestions? Anybody?
