I am using python 2.7 and I am trying to pip install imposm.parser. 
The first thing I did was to install protobuf with pip install protobuf. That installed version 2.6.1 in C:\Python27\Lib\site-packages\google. Then I went here to  download protoc-2.6.1-build2-windows-x86_32.exe which I renamed to protoc.exe and placed in C:\Python27\Lib\site-packages\google folder.
I then installed Microsoft Visual C++ 9.0 from here
Finally, I executed pip install imposm.parser and this is the error I get:

Edit: The header header file saying that is missing is from protobuf which I just installed with pip install protobuf. The file missing is right here in the github google/protobuf/stubs/common.h shouldn't it exist on my system since I installed with pip ? I don't understand...
