failing tests of 0.8.2 with python3.2 and numpy 1.7.1

Wed Jun 12 23:23:25 EDT 2013

The first three are inplace division casting errors supposedly fixed two 
years ago, according to the 4th and 5th posts in 
https://github.com/numpy/numpy/pull/99. Are you sure you're using NumPy 
1.7.1, not something older like 1.5.1? An older version might explain the 
other error as well (harder to pin down without the old/new shape tuples).

What does `import numpy; numpy.__version__` return using the same python 
you tried to build with?
