From your README and wscript I don't see what numpy version you're using to compile scipy against. I got the impression that you used 1.8.1, but it should be numpy 1.5.1 for the 2.7 build, and 1.7.1 for 3.x.
I've tried the scipy 0.14.0 python2.7 wheel, but I get import errors (see below). Your wheels should work with all common Python installs (mine is homebrew) right?

That is strange homebrew is one of tests in the grid and the installation path looks strange.
Can you try downloading the wheel from the url and installing from the local file?
That's what I did (easier than remembering the magic pip incantation). The install path looks fine to me, maybe homebrew changed it recently? I can try to update my install, will take a few days though.
Yes, sorry - that does look like the normal homebrew install path, I didn't realize it had the exotic framework parts to it.
I just ran these commands on my machine:
SPI=https://nipy.bic.berkeley.edu/scipy_installers BREW_BIN=/usr/local/Cellar/python/2.7.6/bin curl -O $SPI/numpy-1.8.1-cp27-none-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.whl curl -O $SPI/scipy-0.14.0-cp27-none-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.whl $BREW_BIN/pip install numpy-1.8.1-cp27-none-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.whl $BREW_BIN/pip install scipy-0.14.0-cp27-none-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.whl $BREW_BIN/python -c "import scipy; scipy.test()"
and the scipy tests passed.
I built the scipy wheel against numpy 1.8.1 - but - aren't the numpies binary compatible? What difference would I expect to see if I'd built scipy against numpy 1.5.1 or 1.7 ?
I summarized here what David explained a while ago about the difference between forward and backwards binary compatibility

I see - thanks for the summary. I will recompile.
Last call - binaries recompiled, tested, more comments here:
https://github.com/numpy/numpy/issues/4007
I'm planning to upload these binaries to pypi later on today,
Cheers,
