You can pass the array in explicitly (param array), then convert it on
output (.tostring() for numpy).  If you have numpy installed and the
code isn't picking it up, then we have another failure case :( .  You
could also just copy the wrapper function from bzr into your code, it's
just a regular python function wrapper; however, if you have numpy, then
it should have picked that up as your default output array format
(generic preferences are numpy, numeric, ctypesarrays, and since *noone*
has Numeric any more, that's just numpy or ctypes arrays).

You can *explicitly* set your preferred handler with
OpenGL.arrays.arraydatatype.ArrayDatatype.registerReturn( 'numpy' ), but
since that's the default anyway, it *shouldn't* make a difference, and
it will still try the others if it can't find your preferred format.

My guess is that numpy isn't importable/usable, and you fell through to
the ctypes arrays. If not, we need to spelunk.
The numpy on my machine is seriously broken--which might be due to a nonstandard Python setup. I'm on Windows, and all the Pythons wanted to install themselves to the registry in the same place. I fussed around with it a while ago, and now double-clicking on a file runs it with Python 2.7, while IDLE is Python 3.3. In fact, if I recall correctly, the NumPy installers that come for Windows couldn't find any Python on the computer at all, nor would they let me tell them where it was. I was annoyed about the whole thing, but didn't (and still don't) have time to untangle the mess.

May I recommend a feature to convert the result directly to a Python string or something for those of us without NumPy?
