Unfortunately I cannot test this patch with different MKL versions or
under Windows. But the current code is clearly broken for an important
case, namely the newest (or even second newest) MKL generation on Linux
(and probably on windows as well from what I understand).
Unless there is a way to work around the problem by static linking I would
be +1 on including a similar patch. I do not know how to make it work on
python 2.4 but I am happy to test any alternative on 2.6 of course. In the
worst casepython 2.4 would fall back to the current behavior if ctypes is
