I have a app.spec-file shown with details here Run Python binaries under Windows XP
when I built a project with PyInstaller 2.1 I saw only: 
- PyQt4.QtCore.pyd
 - PySide.QtCore.pyd
 - PySide.QtGui.pyd
 - PySide.QtNetwork.pyd
 - PySide.QtWebKit.pyd
 
Now, after building with PyInstaller 3.0 I saw additionally:
- qtcore4.dll
 - qtgui4.dll
 - qtnetwork4.dll
 - qtopengl4.dll
 - qtsvg4.dll
 - qtwebkit4.dll
 - qtxml4.dll
 
What is correct fix for avoiding adding QT-libs and importing original PySide libraries only?
