Thanks Deepak. 

You're right that it probably doesn't relate to this problem, but I will keep it in mind if/when this problem gets worked out. 

Thanks again,

So the .egg file exists, but is not a folder, and when make tries to look into the folder that doesn't exist, it can't find the file. But the .egg file works just fine, as shown below (import works just fine in Python).
