See the links that Wes posted for more details, or try pip installing Numpy and Scipy in a new virtualenv, and see what happens.
Probably needs to:
pip install --only-binary :all: numpy scipy
Pip doesn't build from source by default - here's the output from my machine just now:
$ pip install numpy scipy Collecting numpy Downloading https://files.pythonhosted.org/packages/4a/2e/cf0a2fea6d97604a0e058e804b50d5...

Hard to argue with concrete data -- my bad!
I wonder if there's an OS dependence here, though -- I'm almost certain I've had to use `--only-binary` in the past, to avoid pip on my Windows machines trying to download and build sdists, even when wheels were available.
