ошибка: Не удалось найти vcvarsall.bat при установке PyMSSQL-2.0.0b1, что мне не хватает?

Ну, я пытаюсь установить PyMSSQL-2.0.0b1 и не могу этого добиться, получаю странные ошибки... я пробовал некоторые решения, найденные в Google и StackOverflow, но все еще не могу скомпилировать...

пожалуйста, что мне не хватает?

(поэтому я пробовал:

- to add --compiler=mingw32 after setup.py install build 
- to create a distutils.cfd file in Python27\lib\distutils\distutils.cfg with 
    [build]
    compiler=mingw32

и до сих пор не работает)

(также я на Windows 7, и мне нужны сторонние библиотеки, я должен придерживаться 32-битной версии и 2.7)

вот лог с ошибками:

РЕДАКТИРОВАТЬ: похоже на открытую проблему, связанную с http://bugs.python.org/issue12641 и часть '-mno-cygwin' (кстати, если я правильно понимаю)
