[Numpy-discussion] Numpy 1.5.1 test failures

[Mark Dixon]

Hi,

Sorry if this is a noob question, but I've been trying to install Numpy 
for a while now and I keep having problems getting it to pass the test 
suite.

I'm on a RHEL5 system, building against Python 2.6.5 (self-built 
with GCC 4.1.2), gfortran 4.1.2 and MKL 10.3 Update 2 (shipped with Intel 
compiler 2011.2.137).

I'm failing the following tests (see below for full output):

   FAIL: test_complex (test_numeric.TestCorrelate)
   FAIL: test_complex (test_numeric.TestCorrelateNew)

The imaginary components for the results of test_numeric.TestCorrelateNew 
have the correct magnitude but the wrong sign, and 
test_numeric.TestCorrelate is just wrong wrong wrong.

Is this a known issue? searching for test_complex in the mail archive 
didn't find anything.

Thanks,

Mark
