Just to show that this is the new version, I added two print
statements in the 'get_shared_lib_extension' function:
>>> from numpy.distutils.misc_util import get_shared_lib_extension
>>> get_shared_lib_extension(True)
first so_ext .cpython-32mu.so
returned so_ext .cpython-32mu.so
'.cpython-32mu.so'
>>> get_shared_lib_extension(False)
first so_ext .cpython-32mu.so
returned so_ext .so
'.so'

The reason for the same location is obvious because all the patch does
is move  the code to get the extension into that function. So the
'get_shared_lib_extension' function returns the extension '.so' to the
load_library function. However that name is wrong under Linux as it
has to be 'multiarray.cpython-32mu.so' and hence the error in the same
location. I did come across this thread
'http://bugs.python.org/issue10262' which indicates why Linux is
different by default.

So what is the actual name of the multiarray shared library with the Mac?
If it is ' 'multiarray.so' then the correct name is "libname +
sysconfig.get_config_var('SO')" as I previously indicated.
