[Numpy-discussion] ANN: Numpy 1.6.0 release candidate 2

[Ilan Schnell]

I'm seeing these three failures on Solaris 5.10 (x86_64, using Python 2.7.1):

======================================================================

Ran 3152 tests in 16.990s


I'm not sure what the state of Solaris support is these days, but
I remember being able to run all tests without any failures.
