Anyone built PyIlmBase on win32 / x64 w/boost 1.50 and MSVC 2013?

Hi,

  I'm wondering if anyone has successfully used PyIlmBase on windows 
compiled with the following specifics:
     * Microsoft Visual Studio 2013
     * Boost 1.50
     * 64 bit builds (x64)

  I've got it to the point where I can import imath, but an exception is 
being thrown in register_functions, which is then swallowed.  The end 
result looks like this:

 >>> import imath
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
AttributeError: 'NoneType' object has no attribute '__dict__'
 >>>

As far as I can tell, the exception is generated in 
PyImathAutovectorize.h, generate_bindings_struct<class Op, class 
Vectorizable, class Keywords>::apply in its for_each loop.

If anyone has any idea what could be going on it would help me greatly!

Cheers,

-Brett
