If Python is not found on a system, do we still try to run configure.py?
I can test this on Linux at some point, but I guess the best on all
platforms is to then not even try to run configure.py and instead give a
clear message "Python not found. LyX will not work correctly.", and then
maybe link to platform specific info on what to do if Python is not
found.

In any case, this definitely seems tricky.
