I've seen this error before, and I think cleaning up all sphinx caching and
temporary files "fixed" it.
Try running a python make.py clean before building the documention.

Well, I see it this way -- for high performing Python code, you often
need to "vectorize" operations one way or another. i.e. if you need to
do a given operation on a bunch  of numbers, objects, whatever, you
need to be able to pass the collection in to lower-level code, so you
dont have all the overhead of python funciton calls, dynamic typing,
etc, inside your loop.

Many (most) C libraries are not designed this way. So when writing
python wrappers, you need to loop though a sequence in python, and
call the underlying c function for each item. With ctypes, you write
that code inPython, with cython, it's easy to write that code in
cython, which gets compiled down to C -- you can get major performance
benefits from this.

And Cython is almost at easy to write as Python.

How this applied to freetype, I don't know.

you can do this with ctypes, and would work fine for image buffers, by
many not as well as Cython for say, a large sequence of characters...

No, there was no such message.  That is all that was displayed to my screen.

Any chance you can get the full traceback?  I've always seen Sphinx say 
"for the full traceback, see this file..."  Is it not displaying 
anything like that for you?
