Installing pptx via pip for enthought canopy error

I'm having trouble getting pptx set up to work with enthought canopy (I'm using Windows 8).

During installation using pip the following exception occurs. Notice that Pillow is uninstalled before the exception occurs. This is the only thing I can think that has gone wrong.

The full debug log is available upon request. Typing import pptx in canopy currently yields: ImportError: No module named _util

I'm thinking it's just a matter of mismatched directories, but I'm not sure how exactly to check if that's the case

I can reproduce this problem when Canopy is running, but not when Canopy is not running.

Presumed reason: You can't replace the _imaging.pyd file (which is a Windows .DLL) when it is in use.

So quit Canopy and try again.

What the consequences will be for other packages that use PIL, I have no idea.
