ImportError when using cx_Freeze with scipy

Question

I'm trying to use cx_Freeze to generate a .app from a python project. Generally I have it working, but some of my modules which depend on scipy have an import error when executed:

No module named '_csr'

under the build folder I see a file:

scipy.sparse.sparsetools._csr.so

and watching the output of the build command seems to suggest that it's copying csr:

$ python3 setup.py bdist_mac | grep csr
m scipy.sparse.csr          /usr/local/lib/python3.3/site-packages/scipy/sparse/csr.py
m scipy.sparse.sparsetools._csr /usr/local/lib/python3.3/site-packages/scipy/sparse/sparsetools/_csr.so
m scipy.sparse.sparsetools.csr /usr/local/lib/python3.3/site-packages/scipy/sparse/sparsetools/csr.py
? _csr imported from scipy.sparse.sparsetools.csr

copying /usr/local/lib/python3.3/site-packages/scipy/sparse/sparsetools/_csr.so -> build/exe.macosx-10.8-x86_64-3.3/scipy.sparse.sparsetools._csr.so

The problem seems to be related to this other question but that user seemed to solve it by building again, which hasn't helped here. Any ideas?

UPDATE

I mucked around in the .app package contents and found that renaming scipy.sparse.sparsetools._csr.so to _csr.so solves that error (though generates another similar one for another scipy component). It seems like the cx_Freeze script is not properly naming scipy inputs.

Also, here are the versions I'm using:

• cx_Freeze: 4.3.2
• scipy: 0.13.0
• python: 3.3.2
