PyQt5 won't install for Python 3

Question

I'm trying to install PyQt5 desperately. So far I've tried it on OSx Mavericks, an Ubuntu VM and a W7 VM. Nothing seems to work. This is what I've tried.

OSx

I've tried Homebrew

brew update
brew install PyQt5

Output from brew install command:

I've tried all the issues and the troubleshooting. Nothing seems to help.

I also tried to install it manually: sudo python3 configure.py --qmake=/Users/Thomas/Qt/5.1.1/clang_64/bin/qmake --sip=/Users/Thomas/Downloads/sip-4.15.3/sipgen/sip

Works fine. Then, when I try sudo make it keeps giving me:

    In file included from ../../../../Qt/5.1.1/clang_64/include/QtCore/qglobal.h:70:    
../../../../Qt/5.1.1/clang_64/include/QtCore/qsystemdetection.h:243:6: warning:     
      "This version of OS X is unsupported" [-W#warnings]    
      #    warning "This version of OS X is unsupported"    
     ^    
     1 warning generated.

I would think this warning doesn't matter because qglobal.h defines the max-version as 10.8, while I run the 10.9.

sudo make install doesn't give me any errors but when I try to run Python as super user ( sudo python3 ), and try dir(PyQt5) Python crashes. Note that the package is found.

Read somewhere that I need the Python Development Header. So I compiled Python3.3.2 from source on OSx. This gives me nothing better..

Windows

Haven't tried this much. Seems to install with the binary GUI installer. Problem here is that dir(PyQt5) lists some default Python stuff (with the underscores), but nothing actual from Qt*.. Don't know much about Windows and I don't want to (VM is really slow).

Ubuntu

No errors or warnings during install (exact same commands as used during OSx install process), but Python also breaks when I try dir(PyQt5) . No error or whatsoever.

I've tried searching every error I got, some results got me going again. Though, this is where I get stuck and probably stop. If anyone know anything, please help.

It is impossible to install PyQt5 in Mac OS X (including Yosemite) by standard/easy ways at this moment. I've tried everything but only one thing worked - compiling and install it. In this action here is nothing hard to do, I wrote a gist with steps to install pyqt5 on Yosemite.
