Hi,
Following the discussion on python 2.6 support for numpy, I tried last
svn on mac os X, and I get a number of failures which I don't
understand, which seem to be linked to dtype code, more exactly to
endianness:
======================================================================
FAIL: test_basic (test_multiarray.TestClip)

Does anyone have a clue about where to look at ? I am wondering why it
only appears on Mac OS X,
