Build command was:
env ATLAS=/usr/lib64 FFTW=/usr/lib64 BLAS=/usr/lib64 LAPACK=/usr/lib64
CFLAGS="-mtune=native -march=native -O3" LDFLAGS="-Wl,-
rpath=/opt/intel/mkl/lib/intel64" python setup.py build

This command never worked: you need to add the -shared flag to LDFLAGS (and you may want to remove rpath to MKL if you use ATLAS).
