Ah. I've just realised that we're using a MacPython build compiled with
gcc-3.3 but our default compiler is 4.0.1. This could be causing an
issue. Let me try building the extension with gcc-3.3 and, if I can
find one, upgrading python to a version compiled with 4.0 (I really
don't want to have to do a framework python build from source though).

Python 2.4.1 (#2, Mar 31 2005, 00:05:10)
[GCC 3.3 20030304 (Apple Computer, Inc. build 1666)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> numpy.__version__
'1.0.dev3390'
>>> numpy.array([1000],dtype=numpy.longfloat).itemsize
16
