64-bit SciPy.FFTPack for Windows?

Question

I used to have scipy.fftpack available on 32-bit Python 2.7, but now that I upgraded to 64-bit Python and got SciPy from here, I noticed it doesn't seem to include FFTPack.

Where can I download it?

Oh, and the error is:

>>> import scipy.fftpack
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Program Files\Python 2.7\lib\site-packages\scipy\fftpack\__init__.py", line 95, in <module>
    from basic import *
  File "C:\Program Files\Python 2.7\lib\site-packages\scipy\fftpack\basic.py", line 11, in <module>
    import _fftpack
ImportError: DLL load failed: The specified module could not be found.

That build of scipy requires [Numpy-MKL](http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy), which includes the Intel runtime libraries. — cgohlke, Oct 27 '12 at 19:28
@cgohlke: :( do you happen to know of any other build that doesn't? — user541686, Oct 27 '12 at 19:37

Never mind, ProcMon helped me finally figure it out.

It turns out that that version does include FFTPack, but does not include libmmd.dll, which seems to (?) be part of Intel's Math Kernel Library.

If you have the library available in your PATH then it should indeed work.
