I am running Windows 8.1 64-bit.
I always run Python 2.7 in 32-bit mode
I installed libsass both via PIP & via the downloaded wheel.
Both times it fails in the same way when I try to import sass:

import sass
Traceback (most recent call last):
File "", line 1, in
File "c:\bin\python27\lib\site-packages\sass.py", line 21, in
from _sass import (OUTPUT_STYLES, SOURCE_COMMENTS, compile_dirname,
ImportError: DLL load failed: The specified module could not be found.

_sass.pyd is present in the same folder as sass.py

I don't have any Visual Studio to try & compile a version myself.
Are there any Win32 libs which I need installing on my system to get this working?
