Hi Tom,

1) Make sure that you are NOT inside the unpacked sources; to be safe, do a 'cd 
~' or similar.

2) Just FYI: There's currently no official Python 3 version so I wouldn't count 
on it working with Python 3 (see Issue 132).

My suspicion is that it is (1) because the compiled code will not be found in 
the sources.

If this is not that then please continue with this issue report.

Hi,

Given the path in the traceback 
("/sansom/n15/shil3498/Downloads/tmp/MDAnalysis-0.8.1/MDAnalysis/__init__.py"), 
I think that Oliver is right about you being "inside the unpacked sources".
Yet, I suspect that the true problem is due to Python 3: I am the one working 
on Py3 support and I can assure you that, currently, there is no version of 
MDAnalysis (including the one in development) that can handle Python 3. As a 
matter of fact, there a couple of extension that need to be rewritten in order 
to support (ultimately and seamlessly) both Python 2 and 3.
So in short, get out of the source dir, use Python 2 and everything should be 
fine.

Please drop an email if everything is working so we can tag this issue as 
"fixed".
