My team is trying to implement the nao_openni package from WPI(code here). Following the readme file we've gotten to step 5e, where we get a python import error.

"$ rospack find [PACKAGE]" finds the all packages that it says it depends on.

"$ echo $PYTHONPATH" returns:

/opt/ros/cturtle/ros/core/roslib/src:/home/[username]/Desktop/aldebaran-sdk-1.6.13-linux-i386/lib

The error when running:

"$ ./nao_ni_walker.py" (and ./nao_walker.py and ./nao_sensors.py) is:

File "./nao_walker.py", line 51, in <module> from nao_ctrl.msg import MotionCommandBtn ImportError: No module named nao_ctrl.msg

We aren't very familiar with Python, I've been trying to read about it to figure out what's going on but it hasn't been working so far.

We're fairly new to ROS, so any help would be appreciated.

I believe my teammate did it before, is there a way that to check to see that it's been done before?

If you're unsure, it's best to just run the command again.

When running rosmake nao_ctrl there are errors that say gcc is broken, the interesting part can be found here: http://pastebin.com/ZmqKa0vJ. EDIT: There seems to be something wrong with the permissions too.

You likely don't have permissions to write to that directory (check with 'ls -lh /opt/ros/cturtle/stacks/nao_0.2'). If you installed nao_ctrl from a source checkout, you should install it to a directory that you have write access to. You could also try running 'sudo make' to force a make to happen.
