Created attachment 277635 [details, diff] Respect PYTHONDONTWRITEBYTECODE environmental variable in PYTHON_INSTALL macro cmake/modules/PythonMacros.cmake defines PYTHON_INSTALL macro. This macro should not create/install byte-compiled Python modules (*.pyc) when PYTHONDONTWRITEBYTECODE environmental variable is set.
Thanks - fixed in kdelibs-4.6.3-r3, 4.6.4-r1 and later.
