 I have built numpy from the master branch source today (I make new builds
 every couple of weeks), and am seeing a new warning that I have not seen
 before:

 In [1]: import numpy
 /Library/Python/2.7/site-
 packages/numpy-1.7.0.dev_0c5f480_20120412-py2.7-macosx-10.7-x86_64.egg/numpy/random/__init__.py:91:
 RuntimeWarning: numpy.ndarray size changed, may indicate binary
 incompatibility
   from mtrand import *

 I am using the same build script as I always do. I am on OS X 10.7.3, and
 am using the following env variables:

 export MACOSX_DEPLOYMENT_TARGET=10.7
 export CFLAGS="-arch x86_64"
 export ARCHFLAGS="-arch x86_64"
 export FFLAGS="-static -ff2c"
 export LDFLAGS="-Wall -undefined dynamic_lookup -bundle -arch x86_64"
 export PYTHONPATH="/Library/Python/2.7/site-packages/"
 export CC=gcc-4.2
 export CXX=g++-4.2

 Again, nothing has changed here since last I built the package, which did
 not have this message last time.
