#1642: Undefined symbols when trying to build 1.5.1rc1
 Reporter:  opk              |       Owner:  cdavid
     Type:  defect           |      Status:  new   
 Priority:  normal           |   Milestone:  1.5.1 
Component:  numpy.distutils  |     Version:  devel 
 Keywords:                   |

  * status:  needs_info => new


 This particular configtest has the outward appearance of being broken
 rather than of failing so I was assuming the build had failed. Autoconf
 manages to handle failing tests in a rather less alarming way, printing
 just yes or no, so if this is just a no it'd be nice if it looked less
 fatal. It seems numpy may have gone on to build fully. I just tried to
 install it and run the tests. (Is there a way to run the test cases from
 the build directory without first installing?)

 From the test cases I get one failure and some warnings. The warnings are:
   Warning: overflow encountered in ldexp
   Warning: invalid value encountered in power

 The failure is:
 FAIL: test_special_values (test_umath_complex.TestClog)
 Traceback (most recent call last):
   File "/opt/csw/lib/python/site-packages/numpy/testing/decorators.py",
 line 215, in knownfailer
     return f(*args, **kwargs)
   File "/opt/csw/lib/python/site-
 packages/numpy/core/tests/test_umath_complex.py", line 173, in

     raise AssertionError(msg)
 Arrays are not almost equal
  ACTUAL: array([-inf+0.j])
  DESIRED: (-inf+3.1415926535897931j)

 config tests failing are:
