AttributeError: module 'os' has no attribute 'uname'

[Zenahr Barzani]

The thing that strikes me as weird is that I don't have any calls on uname from the os module since I've replaced all os.uname() calls with platform.uname().

here's the error message

I switched os.uname() with platform.platform() and it worked. Now I'm dealing with a character encoding issue during the setup script
