But now setup.py still complains: error: Unable to find vcvarsall.bat and I think it is looking for C:\Program Files (x86)\Microsoft Visual Studio 9.0 while that file got installed in C:\Program Files (x86)\Microsoft Visual Studio 10.0 I don't know how to get the "log.debug" messages from the setup.py script activated... ? Still trying ....
