update, with revision 7769:

Ran 2335 tests in 13.250s
FAILED (KNOWNFAIL=7, SKIP=1, failures=2)

======================================================================
FAIL: test_special_values (test_umath_complex.TestClog)

some examples based on test_umath_complex.TestClog
show differences between complex128 and complex64

I also ran the test of some old scipy against the trunk numpy:

scipy.0.7.0('4826') finishes tests with some display errors
scipy0.7.1rc3 test suite crashes
both scipy versions build by David, according to  __config__.py

(scipy build against trunk a week ago has no problems)
