Just a wild guess:
(1) update your pip and try again
(2) use the bitbucket wheels with: pip install --no-index -f https://bitbucket.org/carlkl/mingw-w64-for-python/downloads numpy pip install --no-index -f https://bitbucket.org/carlkl/mingw-w64-for-python/downloads scipy
(3) check if there i something left in site-packages\numpy in the case you have uninstalled another numpy distribution before.

I took time to create mingw-w64 based wheels of numpy-1.9.1 and scipy-0.15.1 source distributions and put them on https://bitbucket.org/carlkl/mingw-w64-for-python/downloads as well as on binstar.org. The test matrix is python-2.7 and 3.4 for both 32bit and 64bit.
Feedback is welcome.
The wheels can be pip installed with:
Some technical details: the binaries are build upon OpenBLAS as accelerated BLAS/Lapack. OpenBLAS itself is build with dynamic kernels (similar to MKL) and automatic runtime selection depending on the CPU. The minimal requested feature supplied by the CPU is SSE2. SSE1 and non-SSE CPUs are not supported with this builds. This is the default for 64bit binaries anyway.
According to the steam hardware survey, 99.98% of windows computers have SSE2. (http://store.steampowered.com/hwsurvey , click on "other settings" at the bottom). So this is probably OK :-).
OpenBLAS is deployed as part of the numpy wheel. That said, the scipy
wheels mentioned above are dependant on the installation of the OpenBLAS based numpy and won't work i.e. with an installed numpy-MKL.
This sounds like it probably needs to be fixed before we can recommend the scipy wheels for anyone? OTOH it might be fine to start distributing numpy wheels first.
For the numpy 32bit builds there are 3 failures for special FP value
tests, due to a bug in mingw-w64 that is still present. All scipy versions show up 7 failures with some numerical noise, that could be ignored (or corrected with relaxed asserts in the test code).
PR's for numpy and scipy are in preparation. The mingw-w64 compiler used for building can be found at https://bitbucket.org/carlkl/mingw-w64-for-python/downloads.
Correct me if I'm wrong, but it looks like there isn't any details on how exactly the compiler was set up? Which is fine, I know you've been doing a ton of work on this and it's much appreciated :-). But eventually I do think a prerequisite for us adopting these as official builds is that we'll need a text document (or an executable script!) that walks through all the steps in setting up the toolchain etc., so that someone starting from scratch could get it all up and running. Otherwise we run the risk of eventually ending up back where we are today, with a creaky old mingw binary snapshot that no-one knows how it works or how to reproduce...
I tried and failed, even after adding --pre.

Do you have any suggestions?
