Comment(by embray):

 I played with this a bit today and made some progress with the following
 small diff to the main setup.py:

 {{{

 This gets me a good way into the build, before it finally fails here:

 Not sure why that would happen.  When I do a normal `./setup.py build` it
 looks like gcc is outputting some warnings that contain non-ascii
 characters.  But why that's a problem when installing with pip but not
 otherwise isn't clear.
