The code generation logic in numpy does not know anything about
"build_ext --inplace" (which is a distutils feature that develop
invokes). That's it. This problem has always existed for all versions
of numpy whether you use setuptools or not. The logic in
numpy/core/setup.py that places the generated files needs to be fixed
if you want to fix this issue. I'm testing out a fix right now.
