error running ./run_camera.sh

It looks like I was able to compile bgslibrary without it ending with an error.

When I run ./run_camera.sh from its default location with sudo or un-elevated I receive the following error.

Enter to continue...

I am using a virtualenv, but I've tried running it both ways and it yields the same results. I know the camera is working, it runs fine when I'm using cv2/picamera. Also, regardless of what the above output states I am running the version of code downloaded from github and not googlecode. Also, the other demo scripts seems to run without error.

... Now I'm getting this error...
