Intel MKL FATAL ERROR: Cannot load libmkl_mc3.so or libmkl_def.so.

Seems very closely related to #698.

Way to reproduce it:

conda create -n mkl -y python numpy scipy
. activate mkl
python /tmp/test.py

where test.py is:

import numpy as np
from scipy import linalg

y = np.ones(2)
nrm2, = linalg.get_blas_funcs(['nrm2'], [y])
nrm2(y)

Output:

Hmmm by the time I created this issue, the problem disappeared somehow. Oh well, sorry for the noise !
