Yeah, that change just makes sure that Pâté can only be compiled with
python 3.4, and that there are no superfluous compile time checks which
assume it can be compiled with python <3.3 or even python 2.

i'll commit it tomorrow :)

if you all really want, we *could* change the version to 3.3 (as that's the
version where at least all compile time switches can be removed), but as i
said: i'm of the opinion that the hassle of compiling python 3.4 now is
outweighted by being able to use 3.4 features in the years between KF5 and
KDE 6.

just do the following, and you have python 3.4 in a place where it doesn't
interfere with your system python at all:

./configure --prefix=/usr/local --enable-shared LDFLAGS="-Wl,-rpath
/usr/local/lib"
make && make altinstall

then you can call cmake with the variables PYTHON_LIBRARY (and possibly
PYTHON_INCLUDE_DIR) set (see output of: cmake --help-module FindPythonLibs)

best, phil
