I'm running a system wide kde 4.2 installation and a SVN version build by kdesvn-build ind my test users home directory. Installing kdelibs fails with:

-- Installing: /usr/lib64/python2.5/site-packages/PyKDE4/plasmascript.py
CMake Error at workspace/plasma/scriptengines/python/cmake_install.cmake:60 (FILE):
  file INSTALL cannot copy file
  "/home/fhellmut/kdesvn/kdebase/workspace/plasma/scriptengines/python/plasmascript.py"
  to "/usr/lib64/python2.5/site-packages/PyKDE4/plasmascript.py".
Call Stack (most recent call first):

  workspace/plasma/cmake_install.cmake:42 (INCLUDE)
  workspace/cmake_install.cmake:76 (INCLUDE)
  cmake_install.cmake:39 (INCLUDE)

Would it be possible to avoid these conflicts between the system wide and user installation by using Python's environment variables PYTHONHOME and PYTHONPATH?

It looks like I'm not the only user experiencing that problem: See the corresponding thread in the kde forums:
