[SciPy-User] numpy - scipy test failure on OSX (git version 10/3/2012)

[Massimo Di Stefano]

i removed the Xcode tools and  I've re-installed the latest Xcode tools, 
the gcc compiler is :


MacBook-Pro-di-Massimo:~ epifanio$ gcc --version
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.9.00)
Copyright (C) 2007 Free Software Foundation, Inc.

it is the same version i had previously … the build give the same errors about array of  negative size and the test fails as before.


so, i decided to give a chance to home brew. 
i installed it and python,
then using the homebrew easy_install executable i installed nose.

building nupy i noticed the same bad log about error array with negative size.
running the test i got this :

.............................................................

so far, .. no lucky.

i'll try to build the 'stable' old bumpy and see what happens.
