....needed .dlls:

- gnu_gettext
- OpenAL32
- pthreadVC2
- SDL
- wrap_oal

apparently not needed to (I just tried to import bpy, nothing else):
- iconv
- libpng
- zlib

> Finally I fixed the problem:
>
> 1) Built with CMake and Visual C++ Express 2008 (MINGW seems not to work
> appropriately for Windows 7 and generates a bpy.pyd file which is not valid,
> see previous mail)
>
> 2) Copied bpy.pyd AND all the other generated dll (except for python32.dll)
> in the same folder (bin) to C.:\Python32\DLLs (or alternatively in
> C:\Python32\Lib\site-packages)
>
> Just copying bpy.pyd is not enough in my case but I neither tried to copy
> just some of the dlls... any suggestions concerning this point is
