EDIT 2013 :

Many of you happen to have problems installing PyQT and ask me questions about the installation process and errors, via e-mails, or in the comment section, please note that I can’t answer all of them, although, if you find a fix to your problem, please  let me know, or add a comment with the fix !  You are probably not the only one with the problem.
