How do I use the Python modules in webports/naclports with the Python interpreter Chrome app?

Webports has projects in the ports directory for Python and several Python modules, including NumPy. The "python" port compiles a Chrome app that runs the Python interpreter in a console window. I'd like to be able to use modules that include native code, like NumPy, in that interpreter.

Here's what I've tried:

make numpy followed by make python (in hopes that the Python build process sees that I've already built NumPy and includes it), which doesn't seem to change anything
Building the python-static package, which fails with a gigantic error message that ends with libppapi_simple_cpp.a: error: undefined reference to 'PSUserMainGet'
Copying out/build/numpy/numpy-1.8.0/numpy/ into the site-packages folder in pydata.tar in the Python app. import numpy fails with an error message telling me not to import NumPy from its source directory.

Copying out/build/numpy/numpy-1.8.0/build/lib.linux-x86_64-2.7/numpy/ (which appears to have compiled .so files in it) into the site-packages folder in pydata.tar. import numpy fails with this traceback:

>>> import numpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/lib/python2.7/site-packages/numpy/__init__.py", line 153, in <module>
    from . import add_newdocs
  File "/lib/python2.7/site-packages/numpy/add_newdocs.py", line 13, in <module>
    from numpy.lib import add_newdoc
  File "/lib/python2.7/site-packages/numpy/lib/__init__.py", line 8, in <module>
    from .type_check import *
  File "/lib/python2.7/site-packages/numpy/lib/type_check.py", line 11, in <module>
    import numpy.core.numeric as _nx
  File "/lib/python2.7/site-packages/numpy/core/__init__.py", line 6, in <module>
    from . import multiarray
ImportError: cannot import name multiarray

I'm using the PNaCL toolchain version pepper_47 inside a Docker container to build the packages, and I'm running the Python app on Chrome 47.0.2526.106 (64-bit) on Xubuntu.

Solution

The raw python port doesn't catch it, but the numpy port was designed to be used with the python-static port, which will build using the modules that have previously been built. This will then assemble a unified static library that will be linked into the .pexe for python. You shouldn't need to copy any module components by hand.
