Hey Ralf,

I am getting a single test failure:

FAIL: test_special_values (test_umath_complex.TestClog)
Traceback (most recent call last):
  File "/home/dwf/pkg/lib/python2.7/site-packages/numpy/core/tests/test_umath_complex.py", line 275, in test_special_values

  File "/home/dwf/pkg/lib/python2.7/site-packages/numpy/testing/utils.py", line 443, in assert_almost_equal
    raise AssertionError(msg)

This is on a Xeon E5540 built against the MKL 11.1, if that matters (I suspect it doesn't).
