Pyside gives "module "QtQuick" version 2.0 is not installed"

[pioupus]

Hi when i try to run my Python code:
@
import sys
from PySide.QtCore import *
from PySide.QtGui import *
from PySide.QtDeclarative import *

class MainWindow(QDeclarativeView):

def __init__(self, parent=None):
    super(MainWindow, self).__init__(parent)
    self.setWindowTitle("Main Window")
    # Renders 'view.qml'
    self.setSource(QUrl.fromLocalFile('test_gui/test_gui.qml'))
    # QML resizes to main window
    self.setResizeMode(QDeclarativeView.SizeRootObjectToView)

[..]
@

with the qml file
@
import QtQuick 2.0
import QtQuick.Controls 1.1
import QtQuick.Layouts 1.1
[..]
@

I get a "module "QtQuick" version 2.0 is not installed" or if i change to QtQuick1.0 I get
"module "QtQuick.Controls" is not installed" I am pretty sure the pathes are not defined well. I am using Ubuntu 12.04 with Qt5.2 installed in /opt/Qt...

If somebody had an idea I would be very happy

thank you,
