Unable to start test manager

[mjnovice]

When I try to invoke the ~/360Degree_Head_Movement_Dataset/PythonInterface$ sudo bash startTestManager.sh I get

Am using boost 1.63. Someone suggested that the link path and discovery path might be different. But I couldn't get further than that. Can someone help ?
