Summary:                    FindPythonInterp.cmake fails to find python version
Description: 
python 2.4.3 does not support a "--version" arg but *does* provide "-V"

also, as written it requires FindPackageHandleStandardArgs.cmake to be located
in the same directory for some reason

patch can be found in Additional Information
